Temperature/Humidity Sensor (Probe)

Engineering & Marketing International

The X-DTHS-P is a new temperature and humidity sensor probe which is used in conjunction with many of the 400-Series, X-600M, and WebRelay-Wireless products. Temperature and humidity are accurately measured, digitized, and sent to the ControlByWeb module over a serial 1-Wire Bus.

  • Temperature Range: -40°C to 80°C (-40°F to 180°F)
  • Temperature Accuracy: ±0.4°C (typ 0°C to 80°C)
  • Lead Length: 10ft (3.04m)
  • Type: Digital 1-Wire (Maxim Semiconductor DS18B20)

One or multiple sensors can be attached to the 1-Wire Bus and its cables can be extended up to 600 feet (approximately 182 Meters) from the module without any loss of measurement accuracy.

The X-DTHS-P comes with two mounting options:

Mounting Clip – For ease of mounting against a surface.
Thru-Wall Mounting Bracket – For HVAC duct monitoring. The bracket has a foam gasket to seal the access hole.

The sensor can be installed outdoors but must be protected from the elements. Install the sensor in a protected location away from rain or direct sunlight.

No additional software, or power supply required. Simply connect and set up on any of our compatible products.

Temperature Sensor Wiring

The sensor has three wires which are connected to a compatible ControlByWeb device. The cable can be extended with additional wire if needed (600ft max).
