Keeping an eye on temperature in remote or harsh locations can be hard. If the sensor fails or sends wrong data, you may lose product quality, waste energy, or miss a safety alarm. The Milesight EM500-PT100-868M-T050, 868MHz Platinum Temperature Sensor solves this by giving you precise, long-lasting readings over a secure LoRaWAN link. It works even when power is limited and the environment is extreme.
Milesight EM500-PT100-868M-T050, Platinum Temperature Sensor with Milesight
You need a sensor that never quits and tells you the exact temperature every few minutes. This device is a LoRaWAN PT100 temperature sensor built by Milesight. It sends data at 868 MHz, stores up to 1,000 readings, and can alert you when limits are crossed. If you have a cold-chain, a factory line, or an outdoor installation, this sensor gives you the confidence that temperature stays where it should.
