TS601 vs EM300-TH: cellular or LoRaWAN temperature and humidity sensor?
Short answer: Both are IP67 temperature and humidity sensors. The TS601 reports over LTE Cat.1 with its own SIM, so it needs no gateway, and adds a light sensor, tilt detection and base station positioning. The EM300-TH reports over LoRaWAN, so it needs a gateway in range, and in return runs far longer on its battery. One sensor on its own points to the TS601; several on one site point to the EM300-TH.
One sensor or many?
Choose the TS601 for a single location with no gateway nearby: a remote cabinet, a vehicle, a consignment or a lone fridge. It takes a Nano SIM, works on LTE-FDD bands B1, B3, B5, B7, B8, B20 and B28, and sends over TCP, UDP, MQTT, AWS or the Milesight Development Platform.
Choose the EM300-TH when several sensors share a site. One LoRaWAN gateway serves them all, with no SIM or data plan per sensor, and the EM300-TH is rated for over 10 years at SF7 with a 10 minute interval.
How they differ as sensors
The TS601 measures -35°C to 70°C, to ±0.2°C between 0°C and 65°C, and humidity to ±2% RH. The EM300-TH measures -30°C to 70°C, to ±0.3°C between 0°C and 70°C, and humidity to ±3% between 10% and 90% RH.
The TS601 adds a light sensor from 0 to 600 lux that reports light or dark, intended for detecting a cargo box being opened, a 3-axis accelerometer for tilt, and positioning from the mobile network with a typical deviation of 1 km on urban main roads.
Reporting and battery
The TS601 has a minimum packet transmission interval of 15 minutes above 0°C and 30 minutes at or below 0°C, stores 5,000 entries, and is rated around 4.8 years over MQTT or TCP at 6 reports a day with positioning disabled. The EM300-TH stores 2,800 entries and retransmits data missed while out of range.
