DC 4V-30V LM35D LM35DZ Digital Temperature Sensor Linear Module LM35 For Smart car

APDS-9900 provides digital ambient light and proximity sensors (ALS), infrared LED and a complete proximity detection system in a single 8 pin package. The proximity function can be carried out with a 100 mm plug and play test (without the windshield) and thus reduces the need for a terminal device or sub assembly plant calibration. From the bright sunlight to the dark room, the detection function can be operated well. Wide dynamic range is allowed, such as mobile phone dark glass after a short distance detection operation. In addition, the internal state machine has the ability to position the device in a low power mode between ALS and proximity measurements, providing a very low average power consumption. ALS can react with brightness after extremely low light conditions or dark panels. 
APDS-9900 digital ambient light and proximity sensors are particularly useful for display management, which aims to extend battery life and provide the best visibility in different light conditions. Display panel and keyboard backlight accounted for the entire platform power up to 30% to 40% . ALS features are ideal for notebook computers, LCD monitors, flat-panel TVs and mobile phones.
Near ground function is especially suitable for near field applications. In the phone, the proximity detection can be placed in the user when the phone in their ears to detect. When using a cell phone to make a call, the device can quickly provide access to the required high repetition rate. This feature provides improved "green" power saving capability and increased security in order to lock the computer in case the user is not present. In the module, the optical lens can increase the efficiency of the transmission and the infrared energy of the receiver, which can reduce the overall power consumption.

This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8 speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic "LM386" amps!
The A and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin  to ground. The output is "Bridge Tied" - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly.
Comes with a fully assembled and tested breakout board. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Speaker is not included, use any 4 ohm or greater impedance speaker.
Output Power: 2.5W at 4, 10% THD, 1.5W at 8, 10% THD, with 5.5V Supply
50dB PSRR at 1KHz
Filterless design, with ferrite bead capacitors on output.

Module function:
This is the I/O extended module, which use for I2C interface, you can use two of the module to extend 8 I/O.
Support cascading, and you can use at most 8 modules to extend 64 I/O at the same time.
Can be changed the address by set toggle switch 
PCB Size: 36 x 16mm/1.41*0.62" 
Every 2 seconds, make P0-P7 port output High level, Low level, and put 3 toggle switches to ON, the address of module is 0x27
 
 
Features:
 
I2C interface, I / O expansion module, two I / O scalability 8 I / O (up to 8 simultaneous use the PCF8574 expanded to 64 I / O)
