Keyestudio ESP-01 DS18B20 Temperature Module+ESP-8266 WIFI Module For Arduino UNO R3

The Keyestudio ESP-01 DS18B20 Temperature Module is a compact, wireless-enabled sensor designed for smart home and Internet of Things projects. Combining a DS18B20 temperature sensor with an ESP8266 WiFi module, it is ideal for South African makers, students, and hobbyists building remote environmental monitoring systems.

Wireless IoT temperature monitoring

Designed specifically for smart home and Internet of Things applications, this module combines a DS18B20 temperature sensor with an ESP8266-01 WiFi module. This setup allows your projects to connect directly to wireless networks for remote data logging.

Automated remote device control

By transmitting real-time temperature data over WiFi, this module lets you trigger and control other connected devices remotely. It is an excellent choice for building automated heating, ventilation, or cooling systems.

Low-power ESP8266 main control

Powered by the ESP8266-01 main control chip, the module operates efficiently on a DC 3V to 3.3V working voltage. This low power requirement makes it suitable for battery-powered or energy-conscious smart home setups.

Dedicated onboard reset button

The module features a dedicated physical reset button to simplify programming, debugging, and system restarts. This onboard control makes it easier to manage your code during development and testing.

Wide temperature measurement range

The integrated DS18B20 sensor supports a measurement range of 55 degrees Celsius to +125 degrees Celsius. This allows for stable temperature tracking across a wide variety of indoor and outdoor environments.

Compact dimensions and weight

With physical dimensions of 42mm by 24mm by 21mm and a weight of just 4.9g, this compact unit fits easily into small project enclosures. It offers a lightweight solution for portable or wall-mounted sensor nodes.
