Wireless Temperature Sensor

About.

The Systems Tech TS-200 is a wireless, WiFi enabled temperature sensor for monitoring refrigeration units and similar equipment. A flat ribbon probe measures from -55 °C to +125 °C with 0.0625 °C resolution, and the unit sticks on the outside of the equipment with a double-sided sticker. It sounds a 70 dB audible alarm and flashes an alarm icon when the maximum or minimum threshold is crossed, and live readings can be integrated into other systems through the API. A LoRaWAN version is also available.

• Wireless, WiFi enabled (LoRaWAN version also available)
• Double-sided sticker for mounting on the outside of a refrigeration unit
• Audible and visual alarm on maximum or minimum temperature
• Real-time updates with API integration
• Power from micro USB, 5 V
