When temperature spikes or humidity climbs unchecked, your equipment can overheat, fail, or lose accuracy, costing time and money. The ATTOM M-S-TH Temperature and Humidity Sensor delivers precise, real-time climate data so you can protect assets, optimise processes and stay compliant with industry standards.
ATTOM M-S-TH Temperature and Humidity Sensor
Unreliable or missing environmental data can lead to product spoilage, equipment downtime and safety hazards. This is especially critical in manufacturing, data centres, cold storage and HVAC systems where even small deviations matter. The ATTOM M-S-TH Temperature and Humidity Sensor eliminates guesswork by providing accurate temperature and humidity readings across a wide range, and it integrates seamlessly into existing Modbus-RTU networks. You gain instant visibility, remote monitoring and the ability to trigger alerts before conditions become damaging.
Key Features of ATTOM M-S-TH Temperature and Humidity Sensor
- Power Supply: 10-15 VDC (Rated: 12 VDC) - flexible voltage options for varied installations.
- Temperature Range: -20 °C to 80 °C - covers most indoor and moderate outdoor environments.
- Humidity Range: 0-100% RH - full spectrum monitoring from dry to saturated conditions.
- Temperature Accuracy: ±0.3 °C (Tested at 25 °C) - delivers trustworthy temperature data.
- Humidity Accuracy: ±3% RH (Tested at 25 °C) - ensures reliable humidity readings.
- Physical Interface: RS485 - robust, long-distance communication suitable for industrial networks.
- Recommended Tandem Nodes: 64 nodes - ideal for medium-size system expansions.
- Maximum Tandem Nodes: 256 nodes - supports large-scale deployments without loss of performance.
- Transmission Distance: 1200 m (with STP network cable) - enables placement far from the control unit.
- Communication Protocol: Modbus-RTU - standard protocol for easy integration with PLCs and SCADA systems.
- Default Baud Rate: 9600 bps - ready-to-run out of the box.
- Selectable Baud Rates: 2400 / 4800 / 9600 bps - adaptable to existing network speeds.
