PH Value Test Module with Rechargeable Probe and PH-4/PH-9.18 Buffer Solution (Temperature Compensated) Previous 
The ENS160 and AHT21 CO2, Temperature, and Humidity Sensor is a highly advanced digital multi-gas sensor specifically designed for indoor air quality testing. The ENS160 optimizes the detection of a wide variety of gases and volatile organic compounds (VOCs) such as toluene, hydrogen, ethanol, NO2, and ozone. This sensor is ideal for use in home and building automation, consumer products, electrical devices, and air purification systems. It provides ease of use, multiple air quality signal options, and easy integration without the need for additional software libraries, making it suitable for fast response systems and robust design implementations.
