The AHT20 is a next-generation temperature and humidity sensor that sets a new benchmark for both size and performance. Encased in a compact, two-row, leadless SMD package measuring just 3x3mm in footprint and 1.0mm in height, it is designed for easy reflow soldering. The sensor outputs calibrated digital signals in standard I²C format, providing accurate and reliable temperature and humidity readings.
Featuring a newly developed ASIC chip, an improved MEMS capacitive humidity sensor, and an integrated temperature sensor, the AHT20 offers significant enhancements over its predecessors. Its performance is more reliable, even in harsh environments, making it a highly stable solution for a wide range of applications.
Each sensor is factory-calibrated and rigorously tested, with the product lot number printed directly on the surface. Thanks to its miniaturization and improved design, the AHT20 provides a higher cost-performance ratio, delivering energy-efficient operation for modern devices. This makes it an ideal choice for applications where compact size, precision, and energy savings are crucial.
The Temperature and Humidity Sensor Model AHT20 is a versatile temperature & humidity sensor used across a wide range of applications including weather stations, greenhouse monitoring, HVAC systems, cold chain logistics, and server room monitoring.
Common use cases:
Building a home weather station with Arduino
Monitoring greenhouse conditions via IoT
Alerting when server room temperature exceeds threshold
This product is ideal for IoT developers, agricultural engineers, and home automation enthusiasts.
Technical Tip: DHT22 offers better accuracy than DHT11. For precision applications, use SHT31 or BME280. Ensure adequate ventilation around the sensor.
