DHT11 Temp & Humidity Sensor Module | Arduino DIY Kit

This DHT11 humidity sensor is a straightforward way to add environmental data to your electronics projects. The sensor comes mounted on a small PCB, making this digital temperature and humidity sensor module simple to wire into an Arduino, Raspberry Pi, or ESP32 for your DIY projects. Features and Benefits - Temperature and Humidity - It combines a thermistor and a capacitive humidity sensor to provide both measurements from a single component, saving space on your breadboard. - Calibrated Digital Signal - The sensor outputs a digital signal, so you don't need to worry about complex analog conversions. This makes it a good starting point for beginners. - Clear Accuracy Specs - It measures temperature with a ±2°C accuracy and relative humidity with ±5% accuracy. This is suitable for most home automation and weather station projects. - Simple 3-Pin Connection - The DHT11 module connects with just power, ground, and a single data pin. This makes the sensor wiring to an Arduino or other microcontroller very easy. Applications - DIY Weather Station - Build a simple device that logs and displays local temperature and humidity data. - Automated Climate Control - Use the readings to automatically turn on a fan, dehumidifier, or heater in a room or greenhouse. - Environment Monitoring - Check the conditions inside a 3D printer enclosure, an electronics storage box, or a musical instrument case. What It Is This DHT11 Temperature and Humidity Sensor Module is a digital sensor designed to measure both temperature and humidity. It operates within a voltage range of 3V to 5.5V. The module provides a digital output, making it straightforward to integrate into various electronic projects. As a digital temperature and humidity sensor, it offers a convenient way to gather environmental data for monitoring and control systems. Key Uses & Applications This humidity sensor module is ideal for use in Arduino DIY Starter Kits, enabling hobbyists and professionals to build projects that require environmental sensing. Its applications include home automation systems, weather stations, and environmental monitoring in small-scale setups. The module can be used to detect changes in humidity and temperature, providing data for automated climate control or data logging. How to Choose When selecting a humidity sensor, consider its compatibility with your existing micro-controller, such as an Arduino DIY Starter Kit. Evaluate the required humidity range, which for this model is 20% to 90% RH, and the temperature range, 0°C to 50°C. Also, check the accuracy specifications: ±5% RH for humidity and ±2°C for temperature. Ensure the output type is suitable for your project. A working sensor is crucial for reliable data collection. Grit / Spec Guide The DHT11 model is a digital temperature and humidity sensor. It measures humidity with an accuracy of ±5% RH across a range of 20% to 90% RH. Temperature measurements are accurate to ±2°C within a range of 0°C to 50°C. The module requires an operating voltage between 3V and 5.5V. Its polymer material construction provides durability for typical DIY applications. Care & Safety To ensure the longevity of your humidity sensor, avoid exposing it to extreme conditions outside its specified operating ranges. Handle the module carefully to prevent damage to the polymer material or internal components. If the sensor provides inconsistent readings, it may be a faulty sensor and should be checked. There is no user calibration process for this specific sensor; its accuracy is factory set.
