AM2302 temperature & humidity sensor Measures -40 to +80 °C temperature; 0% to 100% humidity Fully calibrated One-wire communication Communication pin can be specified Can use 5V or 3.3V power supply
DHT22 click is a temperature and humidity measurement board carrying an Aosong AM2302 sensor (also known as DHT22). It's a low-cost reliable solution that communicates with your target board's microcontroller through a single Serial Data Line. The sensor can detect temperatures between –40 and 80 °C with a half-degree precision. The relative humidity measurement from 0–100% is accurate within 2%.
The sensor's output is in 16-bit resolution. The resulting decimal number is 10 times the actual temperature measurement, e.g. "256" means 25.6 °C. For best results, set up a minimum of two seconds delay between successive readings.
The board has two solder jumpers. One is for choosing selecting which mikroBUS pin (CS or INT) will be used for communicating with the target board's microcontroller. This is in position SDA1 (CS pin) by default. The other solder jumper is for setting the power supply voltage to 3.3V or 5V. This is in the 3.3V position by default.
mikroBUS Click Boards Overview Click boards come with header pins that you must solder yourself. After that, they just plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. The sockets are found on Clicker boards, these mikromedia shields, and development systems from mikroElektronika (V7 systems and later).
You also can connect Click boards to many other popular platforms via these adapters:
- PC — Click USB Adapter (MIKROE-1433)
- Arduino — Arduino UNO click shield (MIKROE-1581)
- Raspberry Pi — Pi click shield (MIKROE-1512)
- BeagleBone Black — BeagleBone click shield (MIKROE-1596)
- STM32F3 Discovery — STM32F3 Discovery Shield (MIKROE-1447)
- STM32F4 Discovery — STM32F4 Discovery Shield (MIKROE-1481)
- Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad — Click BOOSTER PACK (MIKROE-1363)
In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
