1. Product Summary
DHT20 is a new upgraded product of DHT11, 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).The new generation of upgraded products have been improved to make their performance more stable in high temperature and high humidity environments; at the same time, the accuracy, response time, and measurement range of the product have been greatly improved.
Each sensor is rigorously calibrated and tested before leaving the factory to ensure and satisfy customer’s large-scale applications.
2.Main Features
● Fully calibrated
● Digital output, I2C interface
● Excellent long-term stability
