DHT20
DHT20 is a new upgrade of DHT11, equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor, and a standard integrated temperature sensor. It utilizes the standard I2C data output format. The performance and reliability of the upgraded sensor has been greatly improved and exceeds that of the previous generation.
This new product has been improved to make it more stable in high temperature and high humidity environments. At the same time, product accuracy, response time and measurement range have also been significantly improved. Each sensor is rigorously calibrated and tested before leaving the factory to ensure that it meets the needs of customers in large-scale applications.
| Supply voltage | DC : 2.2 - 5.5V |
| Measuring range (humidity) | 0 ~ 100% RH |
| Measuring range (temperature) | -40 ~ + 80 ℃ |
| Humidity accuracy | ± 3 % RH ( 25 ℃ ) |
| Temperature accuracy | ± 0.5 ℃ |
| Resolution | Temperature: 0.01℃ Humidity: 0.024%RH |
| Output signal | I2C signal |
| Shell material | ABS plastic |
Install DHT20 sensors in bedrooms and other areas to monitor temperature and humidity in real time, and when the temperature is too high or too low, actively control the air conditioner or humidifier switch to realize intelligent energy-saving atmosphere control.
This sensors are set up in different cargo areas of the warehouse to detect changes in temperature and humidity, and trigger an alarm or automatically control the ventilation and dehumidification system if the product preservation threshold is exceeded to ensure that the storage environment meets the requirements.
This sensors are arranged around the key cabinets to send out alarms when the temperature or humidity in the server room is too high to protect the normal operation of key server equipment.
Through DHT20 sensor to obtain the temperature and humidity data in the greenhouse, feedback control equipment according to the plant needs to automatically adjust the ventilation, watering, replenishment of light, etc., to achieve intelligent planting.
Utilizing DHT20 to continuously monitor the humidity changes in the drying room, reflecting whether the drying process is qualified or not, if the humidity is too large, then extend the drying time to avoid the products from moisture.
