MIKROE-1798

2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 DHT22 click 2 3 4. Essential features The DHT22 click temperature and 1. Introduction humidity sensor can detect temperatures between -40 and 80 degrees centigrade with a half a degree precision (0.5C). The relative humidity measurement from 0100% is accurate within 2%. Both relative humidity and temperature data Turn the board upside down so that Turn the board upward again. Make sure signals have a 16Bit resolution. To get the bottom side is facing you upwards. to align the headers so that they are accurate data you should set up the interval Place shorter pins of the header into the perpendicular to the board, then solder between individual sensor readings at appropriate soldering pads. the pins carefully. least two seconds apart. DHT22 click is a temperature and humidity measurement board carrying 3. Plugging the board in the AM2302 sensor (also known as click DHT22). Its a low cost reliable sensor Once you have soldered the headers your that communicates with the target board board is ready to be placed into the desired BOARD microcontroller through a single Serial mikroBUS socket. Make sure to align the www.mikroe.com Data Line. You can choose between cut in the lower-right part of the board with the mikroBUS CS or INT pins for the markings on the silkscreen at the DHT22 click manual communicating with the target board mikroBUS socket. If all the pins ver 1.00 microcontroller. The board is designed to are aligned correctly, push the use either a 3.3V or a 5V power supply. board all the way into the socket. 0100000072066 5. DHT22 click board schematic 6. Jumpers AM2302 DHT22 click has two jumpers (zero ohm resistors). SDA SEL lets you select either CS (SDA1) or INT (SDA2) for outputting the one wire signal. The PWER SEL jumper is for choosing between 3.3 and 5V power supplies. VCC VCC VCC VCC VCC J1 7.
