{"title":"Humidity and Temperature Sensor Module","handle":"humidity-and-temperature-sensor-module","url":"/products/humidity-and-temperature-sensor-module","description":"Measure temperature and relative humidity with this simple, Arduino-compatible sensor module based on the DHT22. With just three connections (GND, power, and data), you can read both temperature and humidity from a single I/O pin on your microcontroller. An Arduino library is available to make integration quick and easy.\n\nThe module includes mounting holes for M3 or 1/8\" bolts and a flat rear face, so it can be easily bolted or glued into your enclosure. Designed and made in Australia by Freetronics.\n\nKey Features\n\n\nDHT22 Sensor – Reliable combined temperature and humidity measurement\n\nSimple 3-Wire Interface – GND, power, and a single data line\n\nWide Voltage Range – 3–5 V operation for flexible integration\n\nLow Power – Just 4.3 mA during reads, even less when idle\n\nBlue Power LED – Visual indicator that the module is powered\n\nMounting Holes – M3/1/8\" bolt compatible for secure installation\n\n\nSpecifications\n\n\nTemperature Range: −40 °C to +80 °C (±0.5 °C accuracy)\n\nHumidity Range: 0–100% RH (2–5% accuracy)\n\nSample Rate: 0.5 Hz (one reading every 2 seconds)\n\nOperating Voltage: 3–5 V DC\n\nCurrent Draw: 4.3 mA (reading), less when idle\n\nDimensions: 31 × 23 × 4 mm\n\n\nIdeal For\n\nWeather stations and environmental monitoring\nArduino and microcontroller projects requiring climate data\nGreenhouse and terrarium automation\nIndoor air quality monitoring\n\n\nPackage Contents\n\n1× Humidity and Temperature Sensor Module (DHT22-based)\n\n\nResources\n\nQuickstart Guide (Freetronics)\nSchematic and Reference (PDF)\nDHT22 Datasheet (PDF)\nDesign Files (GitHub)\n","vendor":"Freetronics","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5381,"title":"Default Title","sku":"FT-HUMID","price":12.0,"compare_at_price":17.5,"on_sale":true,"in_stock":true,"available_quantity":8,"option1":"Default Title"}]}
