Description:
 
 
Sensiron Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses.
 
Unlike earlier SHT sensors, this sensor has a true I2C interface, and (bonus!) even with two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.
 
Such a lovely chip - so we spun up a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.
 
 
 
Power Pins:
 
 
Vin - this is the power pin. The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro like for Arduino, use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V
GND - common ground for power and logic
 
 
I2C Logic pins:
 
SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to Vin
SDA - I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to Vin
 
 
Other Pins:
 
ADR - This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45
RST - Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset!
ALR - Alert/Interrupt output. You can set up the sensor to alert you when an event has occured. Check the datasheet for how you can set up the alerts
 
 
 
Package Included:
 
 
1 X Sensiron SHT31-D Temperature Humidity Sensor

Stable and reliable chipset CP2102
USB specification 2.0 compliant with full-speed 12Mbps.
Standard USB type A male and TTL 5pin connector. 5pins for 3.3V,TXD,RXD,GND & 5V
All handshaking and modem interface signals
Baud rates: 300 bps to 1.0Mbps.
Byte receive buffer; 640 byte transmit buffer.
Hardware or X-On/X-Off handshaking supported.
Event character support Line break transmission.
USB suspend states supported via SUSPEND pins.
Temperature Range: -40° to 85°.
Supports Windows 98SE, 2003, XP, Vista, Window7, Mac OSX , Linux 2.6.x and 2.4.36
Maximum baud rate 115200 perfect support! No longer distressed STC12 Series, STC11, STC15 series Burn!

Features:
100% brand new and high quality.
1. Battery type electricity quantity display.
2. Wide application fields: lithium battery.
3. Using Method: connect display board positive and negative port with tested battery positive and negative port, digital tube will display real-time battery electricity quantity.
4. Digital Color: outline red, display block blue (when battery electricity quantity is full, it will be all on).
 
Display Electricity Quantity Parameter: (note:N represents battery quantity) 
1.When battery voltage is over N*3.3V, it will illuminate 1 block electricity quantity. 
2.When battery voltage is over N*3.5V, it will illuminate 2 blocks electricity quantity.
3.When battery voltage is over N*3.7V, it will illuminate 3 blocks electricity quantity.
4.When battery voltage is over N*3.9V, it will illuminate 4 blocks electricity quantity.
5.When battery voltage is less than N*3.3V, 4 blocks display will be off; it represents battery is less than 3.3V, and you can charge the battery.
