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 eight external sensors with optional 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 integrated CO2, RH, temperature and differential pressure are available upon request. 

The SMT-A3 communicates wireless sensor readings to the SMT Building Intelligence gateway. Optional powered repeaters can be used to extend the wireless range.
