Temperature and humidity sensor AHT21 + Air quality sensor ENS160

Temperature and humidity sensor AHT21 + Air quality sensor ENS160

Product information:

The ENS160 is a digital multi-gas sensor designed for indoor air quality measurement and detects a wide range of gases such as toluene, hydrogen, ethanol, NO₂ and ozone. Ideal for applications in smart home, building automation, air purification and consumer electronics.

The AHT21 sensor is a new generation temperature and humidity sensor in a compact 3x3mm SMD package. With calibrated digital output, improved reliability and high accuracy, this sensor is suitable for HVAC, weather stations, medical applications, data logging, and more.

Features:

• ENS160 Multi-Gas Detection: Accurate measurement of multiple gases and VOCs including toluene, hydrogen, etc.
• AHT21 temperature and humidity sensor: temperature accuracy of ±0.3°C, humidity accuracy of ±2% RH
• Dual sensor integration: air quality and temperature/humidity monitoring in one module
• Wide working range: temperature -40~+85℃, humidity 5~95%RH
• Fast heat-up: ENS160 takes less than 1 minute to reach optimum performance
