The onboard DHT11 sensor captures environmental data, which the ESP8266 processes and uploads to a server — perfect for IoT and smart home projects.\n\nSimply program your ESP-01/ESP-01S, plug it into the 2×4 pin header, and connect a DC power source. The module handles the rest, making it an easy starting point for wireless environmental monitoring.\n\n\nNote: The ESP-01/ESP-01S module is not included and must be purchased separately.\n\n\nKey Features\n\n\nDHT11 Sensor – Measures temperature (0–50°C, ±2°C accuracy) and humidity (10–90% RH, ±5% RH accuracy)\n\nWide Input Voltage – Accepts DC 3.7V–12V, compatible with 3.7V lithium batteries for portable use\n\nESP-01/ESP-01S Compatible – 2×4 pin header for easy plug-in of your ESP8266 WiFi module\n\nWiFi Data Upload – Transmit temperature and humidity readings to a remote server wirelessly\n\n\nIdeal For\n\nSmart home environmental monitoring\nIoT temperature and humidity logging\nWireless sensor networks with Arduino or NodeMCU projects\nBattery-powered remote weather stations\n\n\nGetting Started\n\nConnect a 3.7V–12V DC power supply to the VCC and GND pins (2.54mm header)\nDownload and flash your program to the ESP-01/ESP-01S\nInsert the ESP-01/ESP-01S into the 2×4 pin header (follow the arrow direction on the board)\n\n\n\n\nTemperature and humidity data is sent to another WiFi module and displayed via serial output:\n\n\n\n\n\nPackage Contents\n\n1× ESP8266 ESP-01/ESP-01S DHT11 Temperature Humidity Module\n\n\nResources\n\nManual and tech support (GitHub)\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3944,"title":"Default Title","sku":"EC-ESP82003S","price":5.23,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
