Product Manual 2 M3 Wireless Ultrasonic Level Sensor

1.0 Description and General Operation

The Massa Model M-3 Wireless Ultrasonic Sensor consists of a transducer, ultrasonic electronics, ZigBee XBee RF module,

microprocessor, and batteries all housed in a weather tight 2” NPT housing. Different models have different sensing ranges. The

M3 can be programmed to automatically obtain and record range, temperature, battery voltage, sensor parameters, and other

information at a specified rate. Independent to the ultrasonic acquisition is the operation of the ZigBee radio which can be

programmed to sleep for extended periods conserving battery life. When the sensor wakes up from its programmed sleep, it can

be programmed to automatically send the acquired ultrasonic data to the gateway or conversely the gateway can request the data

when it detects the sensor wakes up. The sensor includes a Commission pushbutton switch used to associate the sensor onto the

ZigBee network (if it fails automatically at power up) and a LED is used to identify the operating mode. The package is rated for

high pressure wash-down and is accessible for replacing batteries. The sensor is considered an end device in the ZigBee

environment.

NOTE: The sensor does not contain a power switch. If there is a desire to re-boot the sensor, remove one of the batteries, press

the sensor’s Commission button, and then re-install the battery. The LED will blink green 3 times indicating it was reset. This

procedure is required to discharge circuitry when the sensor is in Deep-Sleep since there is very little current drawn.
