BulletPoint1 : ★The AHT15 temperature and humidity sensor is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard temperature sensing element, and its performance has reached the advanced level in the industry.
BulletPoint2 : ★The improved new generation temperature and humidity sensor AHT15 has more stable performance in harsh environments, and can also maintain good accuracy in a larger measurement range.
BulletPoint3 : ★AHT15 uses standard pitch pin connectors, which can easy to replace.
BulletPoint4 : ★Every sensor is rigorously calibrated and tested.
BulletPoint5 : ★It is precisely because of the improvement and miniaturization of the sensor that it is cost-effective.
BulletPoint6 : 【High Availability】It can operate normally at 110V, 60HZ AC voltage, with the ambient relative humidity less than 85% RH and the temperature range between -10°C and 60°C. Therefore, it applies to most situations.

Interface Definition
1 VDD connect to power supply (2.2-5.5V)
2 SDA serial data, bidirectional
3 GND power ground
4 SCL serial clock, bidirectional

Power Supply Pin (VDD GND)
The power supply range of AHT15 is 2.2-5.5V

Serial Clock (SCL)
SCL is used for communication synchronization between microprocessor and AHT15. Since the gate contains completely static logic, there is no minimum SCL frequency.

Serial Data (SDA)
The SDA pin is used for dry sensor data input and output. When sending commands to the sensor, SDA is active on the rising edge of the serial clock (SCL) and must remain stable while SCL is high. After the falling edge of SCL, the SDA value can be changed. To ensure communication security, the valid time of SDA should be extended to Tsu and Tho before the rising edge of SCL and after the falling edge of SCL, respectively. When reading data from the sensor, SDA is valid (TV) after SCL goes low, and remains until the next fall of SCL.
