₹66
The DHT11 is a basic, ultra-low-cost digital temperature and humidity sensor. It is the perfect entry-level module for adding environmental monitoring capabilities to your custom smart home systems, weather stations, or automated dashboards. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, pushing out a reliable digital signal on the data pin. This makes it incredibly easy to integrate right into your Arduino starter kits or custom ESP-12F based boards without needing complex analog-to-digital conversions. Temperature Range: 0°C to 50°C Humidity Range: 20% to 90% RH Signal Type: Digital Output
