Industrial-Grade Temperature Monitoring Made Simple
The THS-317-ET ZigBee Temperature Sensor from OWON provides precise, real-time temperature data for HVAC systems, cold storage, pipelines, and industrial environments.
Equipped with a 2.5-meter external probe, it enables flexible installation and reliable long-range monitoring.
🌡 Key Features
- Precise Temperature Measurement
Accurately measures temperature for air, liquids, or surfaces — ideal for HVAC ducts, freezers, swimming pools, and more.
- External Probe Design
The 2.5 m remote probe allows placement in hard-to-reach or high-temperature areas while keeping the ZigBee module easily accessible.
- Long Battery Life & Low Power Consumption
Powered by two AAA batteries (user-replaceable) with ultra-low energy design for long-term stability.
- Battery Status Display
Built-in battery indicator helps users check device power anytime.
- ZigBee 3.0 Wireless Connectivity
Operates on the IEEE 802.15.4 2.4 GHz standard, providing stable transmission up to 100 m (outdoors) or 30 m (indoors).

Frequently Asked Questions (FAQ)
Q1: What is the difference between THS-317-ET and a standard ZigBee temperature sensor?
A: The THS-317-ET includes a 2.5-meter external probe that allows accurate temperature monitoring in remote or enclosed environments such as pipelines, freezers, or HVAC ducts — where built-in sensors cannot reach.
Q2: What is the measurement range and accuracy?
A: It measures from -40 °C to +200 °C, with a typical accuracy of ±0.5 °C in the main range (-10 °C ~ +55 °C).
Q3: Can it connect to my existing ZigBee gateway or BMS system?
A: Yes. It is fully compatible with ZigBee 3.0 networks and works with gateways such as Home Assistant (ZHA/Zigbee2MQTT), Jeedom, and Amazon Echo Plus.
(Note: Not compatible with Tuya ZigBee gateways.)
Q4: How is the device powered and how long does the battery last?
A: Powered by 2 × AAA batteries, the sensor features ultra-low power design, typically lasting up to 2 years depending on reporting frequency.
Q5: Is OEM or customization available?
A: Yes. OWON provides OEM/ODM customization, including firmware adjustment, logo printing, and housing design for system integrators and distributors.
