General Information of DHT20 Sensor:
Saftty DHT20 sensor is a new upgraded product of DHT11sensor, equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor, and a standard on-chip temperature sensor, and uses a standard I2C data output signal format.
Its performance has been greatly improved and has exceeded the reliability level of the previous generation sensor(DHT11). As a new generation and upgraded product, DHT20 sensor performances are more stable in high temperature and high humidity environments; meanwhile, the accuracy, response time, and measurement range of the DHT20 have been greatly improved.
Each sensor from Saftty is rigorously calibrated and tested before leaving the factory to ensure and satisfy customers’ large-scale applications.
Applications of DHT20 Sensor:
The DHT20 sensor is a kind of humidity and temperature with digital I²C output. The applications of DHT20 sensor are wide: HVAC, dehumidifiers, testing and inspection equipment, consumer products, automobiles, automatic control, data loggers, weather stations, home appliances, humidity control, medical, and other application fields which need to detect and control temperature and humidity.
