The SMT-A3 Wireless Data Acquisition unit is a multi-channel high precision measurement device designed to interface with a variety of different building sensors. The sleek design of the SMT-A3 allows it to be installed in occupied spaces in building units and homes. The SMT-A3 seamlessly attaches to a double junction box and supports up to four external resistance sensors 3 voltage senors with Carbon Dioxide, Temperature and Relative Humidity integrated sensors.

 

The 24-bit A/D and long range wireless proven on the SMT-A2 platform is duplicated on the SMT-A3 making it ideal for building monitoring in both new construction and retrofit work. Options for differential pressure are available upon request.
