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.

Note
1. The power supply voltage of the host MCU must be consistent with the sensor when the product is used in the circuit.
2. If you need to further improve the reliability of the system, you can control the sensor power supply.
3. When the sensor is just powered on, the MCU will give priority to VDD, and SCL and SDA can be set to high levels after5ms.
* Please contact us directly about Sensor Communication, we will send you the Communication protocol and data sheet.
