The MeshNet Wireless Temperature / Humidity / Pressure / Light Sensor Line, MN-ENV, provides an intuitive way to reliably monitor and control environmental conditions in indoor environments. Wireless transmissions utilize the 2.4GHz frequency range allowing for global usage. Each MeshNet wireless sensor can be tailored through the user defined parameters to provide the appropriate responsiveness & battery life. The wireless sensors provide highly accurate humidity, temperature, barometric pressure and/or light readings; as well as a pulse counter, and a discrete input.

Greater transmission reliability is provided by each sensor (node) having the capability to both transmit and receive data packets. The receiving capability enables sensors to confirm the reception of data transmissions. If confirmations are not received additional transmissions are made on other 2.4GHz channels. All MeshNet devices report the strength of the transmissions they receive, allowing areas that may be susceptible to interference to be identified and addressed proactively (e.g. adding repeaters).

Easy Sensor Setup

Each MeshNet sensor requires a physical connection to the Controller in the initial setup (linking). The linking process allows the sensor and controller to exchange necessary information for joining the unique Wireless network. Since each network has a unique identifier multiple wireless networks can operate in the same vicinity. Sensors can switch networks through repeating the linking process with the new wireless network’s controller. The linking process is completed by following the straight forward steps:

  1. Remove lid from MeshNet Sensor
  2. Take the supplied 3.5mm linking cable (see left) and attach it to the MeshNet Controller.
  3. Attach the remaining right angled 3.5mm plug to the MeshNet Sensor's 3.5mm jack.
  4. Insert the supplied 3.6V AA Lithium Battery.
  5. Wait for the LED to quit blinking. (It will take approximately 5 seconds.)
  6. Disconnect the linking cable from the Sensor and Controller

User Defined Parameters

User definable parameters allow each sensor to be configured to identify and react independently to the alarm conditions. These parameters include High Alarm, Low Alarm, LED Function, Relay Function, Read Period and Transmission Rate. The flexibility in alarm handling and energy consumption are indispensable for many monitoring and control applications.

Alarm Responses - The LED and optional relay response times are extremely fast; the sensors are able to respond appropriately (activate fan/alarm siren/etc) even before the monitoring application is aware an alarm has been triggered.  Since, the Temperature / Humidity / Pressure / Light alarm functions can operate independently of the MeshNet Controller the sensor can be used as a standalone Thermostat, Humidistat or the pressure/light equivalent.
  • Activate when an alarm parameter is met and deactivate when the alarm byte is cleared
  • Activate when an alarm parameter is met and deactivate when readings return to normal range 
  • Controlled independent of alarm status.
 Battery Life Optimization - The MeshNet sensors are designed to maximize battery life. The MeshNet sensors achieve this efficiency by spending the majority of their time in sleep mode. They awake at a user defined rate and calculate the sensor values. Next they transmit the data if an alarm became active or when a transmission was scheduled. The units listen momentarily for a reception confirmation and then return to sleep mode.
  • Sensor Read Frequency - The time between the readings being taken. If an alarm becomes active the data is transmitted. Longer intervals will increase battery life
  • Transmit Frequency - The time between scheduled transmissions. Longer intervals will increase battery life.
  • Discrete Input Alert - When enabled the sensors transmit data as the discrete input state changes. Constant monitoring of the input does not use the internal battery, making it a low power, real-time updated discrete input
