Wireless Temperature Transmitter Overview
A long-range, high-accuracy wireless temperature transmitter designed for continuous monitoring of fridges, freezers, coolrooms, and ambient environments.
Key Features
- Certified sensor accuracy: ±0.2°C
- Long-range wireless: 100–300m open areas, 75–125m indoors, 50–75m inside metal fridges/freezers
- Battery life: 1–3 years, depending on update interval
- Bi-directional communications with the gateway
- Logs up to 1 year of data when out of range; automatically uploads when back in range
- Designed airflow path for accurate sensing (IP rating intentionally modest to allow correct airflow)
- Compact housing suitable for fridge/freezer mounting.
- Glycol bottle response to temperature changes
- Auto timestamping and cloud upload via gateway
