1-Wire Temperature and Humidity Sensor TSM400-1-TH

1-Wire Temperature and Humidity Accuracy

TSM400-1-TH is a digital temperature and humidity sensor featuring a 1-Wire interface. Designed for wall mounting, it's well-suited for monitoring server rooms, data centers, offices, stores, and more.

This sensor integrates essential components and signal processing to deliver highly accurate digital output, eliminating the need for recalibration. It operates on a 1-Wire bus, and each unit boasts a unique 64-bit serial code, enabling support for multiple sensors on the same bus.

Housed in a slim plastic enclosure, the bottom part is designed for installation on standard flush-mounted or cavity wall boxes with a diameter of 68mm and installation openings spaced 61mm apart.

Maintaining humidity levels is crucial for creating a healthy environment in various settings, including offices, workplaces, schools, and public buildings.

Features:

Communication status is displayed through an LED indicator
Provides outstanding long-term stability
Designed for easy wall mounting
Supports firmware updates via the interface
Operates with low current consumption
Unique 64-Bit serial number for multi-sensor compatibility

* Recommended operating range is 20% to 80% RH (non-condensing) over –10 °C to 60 °C
Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.
** Higher drift values might occur due to contaminant environments with vaporized solvents, out-gassing tapes, adhesives,
packaging materials, etc.
