The DHT20 temperature & humidity sensor is the newly upgraded version of the DHT11. Data accuracy, stability, response speed, measurement range are greatly improved up. DHT20 is a brand new ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and a standard on-chip temperature element. All sensors are factory calibrated and characterized by low power, high precision & stability, fast response, and strong anti-interference. Moreover, the DHT20 performance parameters of accuracy, power supply voltage, measurement range and response time have been enhanced greatly over the previous generation, making it more cost-effective.Besides that, the DHT20 temperature & humidity sensor employs I2C digital output protocol, which is very suitable for HVAC, automobiles, data loggers, weather stations, home appliances, and other related temperature and humidity detection and controlled areas.Features * Factory calibration * I2C digital output * Quick response, strong anti-interference ability * Low power, low cost * Compatible with mainboards like Arduino, micro:bit, ESP32, Raspberry Pi * Compatible with 3.3~5.5V main controller Applications * HVAC * Automobiles * Data loggers * Weather stations * Home appliances Specifications * Operating Voltage: 3.3V ~ 5.5V DC * Operating Current: ＜1mA * Output Signal: I2C (0×38) * Temperature Range: -40 ~ +80°C ±0.5°C * Humidity Range: 0~100%RH ±3%RH (25°C) * Resolution: 0.01℃, 0.024%RH * Storage Condition: 10℃-50℃, 20-60%RH * Board Dimension: 22*33 mm/0.87*1.30” * Mounting Hole Size: Inner diameter 3.1mm (0.13”)/Outer diameter 6 mm (0.24”) Documents * Product wiki Shipping List * Temperature and Humidity Sensor x1 * Gravity-4Pin I2C Sensor Connector (30cm) x1 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-01-23 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-04-21 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-09-27 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-09-28 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-10-11 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-10-18 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-11-01 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-12-02 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-12-15 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-12-21 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2025-12-26 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-01-06 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-01-22 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-01-30 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-03-05 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-03-14 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-03-19 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-04-12 https://elecena.pl/product/27744552/dfrobot-gravity-dht20-temperature-amp-humidity-sensor-for-arduino 2026-04-16
