WKBEL-C is a long-range Bluetooth wireless temperature sensor designed for cold chain and IoT temperature monitoring projects. The product features a wireless design that allows for quick replacement of traditional wired temperature probes, reducing installation complexity, the risk of cable aging, and long-term maintenance costs.
The sensor features BLE 5.0 Bluetooth communication technology, with a transmission range of up to 350–400 meters in open areas, making it suitable for multi-point temperature monitoring scenarios such as cold chain transport vehicles, commercial refrigerators, warehousing and logistics, food preservation, and greenhouses. With a built-in 5,400 mAh battery and a low-power design, the device has a service life of approximately 3 years.
The WKBEL-C has a temperature measurement range of -40°C to 80°C, with an accuracy of ±1°C. The device features IP67-rated water and dust resistance, making it suitable for cold storage, high-humidity, outdoor, and complex industrial environments. Users can configure settings and calibrate the temperature using the companion app.
