Descritipion:
The main chip is GY-213V-HDC1080(Can use SHT21 HTU21D SI7021 chip to made the same sensor)
This I2C digital humidity sensor is a fairly accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor - SHT15 Breakout It has a typical accuracy of ±4% with an operating range that's optimized from 10% to 80% RH. Operation outside this range is still possible - just the accuracy might drop a bit. The temperature output has a typical accuracy of ±0.2°C from -20~85°C.
 
The HDC1080 sensor chip has 2 address-select pins, so you can have up to 4 shared on a single I2C bus. It's also 3-5V power and logic safe so you don't need any level shifters or regulators to use with a 5V or 3V microcontroller.
 
Please note: TI has indicated that there's a 'settling' effect for the humidity and that you will need to re-hydrate the sensor once you receive it. To rehydrate it, place it in a location with 85% humidity for 24 hours or 60% humidity for 10 days.
 
The HDC1080 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The HDC1080 operates over a wide supply range, and is a low cost, low power alternative to competitive solutions in a wide range of common applications. The humidity and temperature sensors are factory calibrated.
 
Features:
 
Relative Humidity Accuracy ±2% (typical)
Temperature Accuracy ±0.2°C (typical)
Excellent Stability at High Humidity
14 Bit Measurement Resolution
100 nA Sleep Mode Current
 
Power Pins:
 
Vin - this is the power pin. Unlike many sensors, this chip can be powered by 3-5 VDC, so there is no voltage regulator on board. Simply power the board with the same power as the logic level of your microcontroller - e.g. for a 5V micro like Arduino, use 5V. For a 3V ARM processor, use 3V
GND - common ground for power and logic
I2C Logic pins:
SCL - I2C clock pin, connect to your microcontrollers I2C clock line. 3-5V logic OK
SDA - I2C data pin, connect to your microcontrollers I2C data line. 3-5V logic OK
 
Optional Pins:
 
These are pins you don't need to connect to unless you want to!
RDY - This is the interrupt/'ready' pin from the HDC100x. The chip has some capability to 'alert' you when data is ready to be read from the sensor. We don't use this pin in our library but it's available if you need it! It is open collector so you need to use a pull-up resistor if you want to read signal from this pin.
A0 A1 - These are the address select pins. Since you can only have one device with a given address on an i2c bus, there must be a way to adjust the address if you want to put more than one HDC100X on a shared i2c bus. The A0/A1 pins set the bottom 2 bits of the i2c address. There are pull-down resistors on the board so connect them to Vin to set the bits to '1'. They are read on power up, so de-power and re-power to reset the address
Si7021 humidity and temperature sensor
Description:
 
The main chip of this item is GY-213V-HTU21D 
The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. 
This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems. All you need is two lines for I2C communication and you'll have relative humidity readings and very accurate temperature readings as a bonus!
There are only four pins that need to be hooked up in order to startusing this sensor in a project. 
One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built in 4.7k pull up resistors for I2C communications.If you're hooking up multiple I2C devices on the same bus, you may want to disable these resistors.Dimensions: 0.6 x 0.6"

DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.
   RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus.
   A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply. In addition, / RST pin is monitored as generating μP reset manually.
Save time and high precision addition, DS3231 also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it (as the same time). This temperature sensor accuracy is ± 3 ° C. On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected. When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.

BT5.0 Audio PRO Mini Bluetooth 5.0 MP3 Decoder Board Audio Receiver MP3 Lossless Player Wireless Stereo Music Amplifier Module Lithium battery charging Incoming call
BT5.0 Audio PRO continues the excellent basic functions of M28 (long-distance transmission, Bluetooth 5.0 backward compatible, lossless sound quality, etc.), and adds more user-friendly performance, as follows: Charge while putting: This product has a circuit of charging and discharging, which can directly charge the battery through the USB power supply, and Bluetooth can continue to work normally during the charging process, and truly realize the function of charging and discharging. Solve the pain point that some products can not be used during the charging process. When powered by USB alone: The red light flashes, indicating that the power supply is normal. When powered by a separate battery: The yellow light is always on, indicating that the battery power supply is normal; the yellow light flashes, indicating that the battery is low. When the USB and battery are connected at the same time: The red light flashes to indicate that the battery is charging; the red light always indicates that the battery is fully charged. (Note that if the USB input is suddenly disconnected during the charging and discharging process, there will be a few seconds of interruption due
to the charge and discharge mode switching at this time, after which Bluetooth will automatically restart, automatically connect and maintain the previous playback state) Incoming voice call function: After the Bluetooth is connected, turn on the call audio mode in the Bluetooth settings. If the phone calls, you can answer or hang up the phone through the PLAY/STOP button. You can choose to send from the microphone of the original headset (provided that the headset has a call function, which is a 4-segment type) or from the onboard microphone (default), see the function description for details. When the computer sound card is used: Tin the pads in the two boxes corresponding to the Sound Card on the back of the module, and then connect it to the USB interface of the computer through the USB cable, which can be used as a sound card. That is, the sound played by the computer is output through the audio interface of the module. See function description for details. (Not enabled by default) Product Size:
