Product Description
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.

Features
+
-
Supports up to 8 external resistance channels capable of reading wide moisture content ranges and precision thermistors.
-
Supports up to 8 0-5V sensors such as RH, pressure differential, LVDT, displacement, light sensors and more.

Optional integrated relative humidity and temperature sensors.
-
Sensors are installed using a two part terminal block permitting sensor lengths to be cut to their appropriate lengths and terminated prior to installing electronics.
-
Large internal memory allows an 8 channel unit to log hourly data for up to 3 years without extracting data.
-
Wireless transceiver with 1000m line of sight communication. Optional repeaters can be used to extend the wireless range.
-
Communicates to SMT Building Intelligence Gateway (BiG) via USB to Wireless device; SMT-I2.
-
Extreme low power device and 3 AA battery pack makes the SMT-A3 suitable for long term battery operation.
-
USB connectivity supports data downloads, configuration and firmware upgrades.
-
Backlit LCD user interface for easy network and sensor verification
