The AHT20 probe integrates the proven AHT20 MEMS capacitive sensing chip within a durable, sealed stainless steel housing. This design provides reliable, drift-free measurement of ambient temperature and relative humidity, making it suitable for long-term monitoring in demanding conditions such as HVAC ducts, agricultural greenhouses, and industrial process control.
The sensor communicates via a two-wire I2C interface, outputting calibrated digital data that eliminates the need for external signal conditioning. The attached 1-meter cable allows for flexible placement while maintaining signal integrity, and the probe’s construction ensures resistance to moisture and corrosion.
