The DHT11 Temperature and Humidity Sensor is a commonly used digital temperature and humidity sensor module. It's designed to accurately measure the temperature and relative humidity in the surrounding environment.

Here's a feature of the DHT11 sensor :

Combined Sensor: The DHT11 integrates a temperature sensor and a humidity sensor within a single module. This allows it to measure both temperature and relative humidity simultaneously.

Digital Output: The sensor provides a digital output signal, making it easy to interface with microcontrollers and digital devices. The output signal is in the form of a time-based digital signal that reflects the temperature and humidity readings.

Wide Operating Range: The DHT11 can measure temperature in the range of 0°C to 50°C (32°F to 122°F) with an accuracy of ±2°C. For humidity, it can measure in the range of 20% to 90% RH with an accuracy of ±5%.

Simple Interface: The sensor communicates using a single-wire digital protocol. It requires minimal external components for interfacing, making it easy to integrate into projects.

Low Power Consumption: The DHT11 sensor operates on low power, making it suitable for battery-powered applications.

Factory Calibrated: The sensor is factory-calibrated, which means it should provide reasonable accuracy without the need for user calibration.


Home Weather Stations: The DHT11 is commonly used in DIY weather station projects to measure temperature and humidity levels.

Indoor Climate Monitoring: It's used to monitor indoor temperature and humidity levels for maintaining comfortable living or working environments.

Plant Growth Monitoring: In gardening and greenhouse applications, the sensor helps monitor conditions that affect plant growth.

Great working just fine

Great working just fine. DHT22 has higher resolution. The DHT11 is 1C and 1% steps.The pins are thin so they dont like being pushed into breadboard.

These appear to be fine. Pins are standard thickness for dht 11 and dht 22. That being said they are thin and will not make great contact in a breadboard. Solder on some wires and move along.
