Temperature & humidity sensors from ASAIR
The AHT..., DHT... and AM... series of ASAIR sensors allow for temperature and humidity measurement with a single item.
The sensors with I2C digital output - AHT10 and AHT15 provide accuracy of ±2%RH/±0.3°C and are supplied with 1.8÷3.6V voltage, while DHT10 has an accuracy of ±3%RH/±0.5°C and operates in the wide 2.5÷5.5V voltage range. The AHT15 additionally features a PTFE film protecting the sensor against water and dust, so it can be used in harsh environmental conditions. The AM2120 is also a sensor with digital output, but communication is done via a single-wire interface. The AM1011A features analog output and it is available as a module with cable connection.
The AHS01IB is a 5V-powered absolute humidity sensor with I2C digital output.
Every single sensor is individually calibrated.
