AM2315 Digital Temperature Humidity Sensor
AM2315 Digital Temperature Humidity Sensor is a kind of temperature and humidity sensor with self – calibrated digital signal output. The special temperature and humidity acquisition technology is adopted to ensure that the product has extremely high reliability and excellent long – term stability. The sensor comprises a capacitive sensing element and a high – precision integrated temperature measuring element , and is connected with a high – performance microprocessor.
While it is not rated as ‘weatherproof’, this sensor would do much better for sensing where there might be wind, rain, zombies, etc. than SHT PCB-breakout sensors, and the i2c interface makes it easier to interface with microcomputers that can’t do the delicate timing of the DHT sensors.
Simply connect the red wire to 5V power, black to ground, yellow wire to your i2c data pin, and the white wire to the i2c clock pin. You cannot change the i2c address so only one sensor per i2c bus. Two ~10Kohm pullup resistors are required for use, connect from the SDA and SCL lines to the power wire, the pullup resistors are not included!
