The Grove - Temperature & Humidity Sensor utilizes the upgraded version of DHT11, offering better performance than the previous generation. Featuring a capacitive sensor and built-in ADC for digital output, it provides a humidity measurement range of 5–95% RH (±5%) and a temperature range of -20 to 60°C (±2%). Known for its low cost, stability, and long transmission distance, it is an ideal choice for DIY weather stations, automatic controls, and testing systems.

Comparison: DHT11 vs DHT22
| Item | Grove - DHT11 | Grove - DHT20 | Grove - DHT22 |
|---|---|---|---|
| Humidity Range | 5% ~ 95% RH | 0% ~ 100% RH | 0% ~ 100% RH |
| Humidity Accuracy | ±5% RH | ±3% RH | ±2% RH |
| Temperature Range | -20°C ~ 60°C | -40°C ~ 80°C | -40°C ~ 80°C |
| Temperature Accuracy | ±2°C | ±0.5°C | ±0.5°C |
Note: DHT11 is more cost-effective but has a smaller range and lower accuracy compared to DHT22.
