The MeshNet Wireless Temperature, MN-ENV-T, provides an intuitive way to reliably monitor and control temperature in indoor environments. Wireless transmissions utilize the 2.4GHz frequency range allowing for global usage. Each Temperature sensor can be tailored through the user defined parameters to provide the appropriate responsiveness & battery life. The wireless sensors provide highly accurate temperature 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).
The Gen 1 MeshNet Sensors now features wireless linking, which eliminates the need for a physical connection between the MeshNet Controller and the MeshNet Sensor during the initial setup. The wireless linking process allows the sensor and controller to exchange all necessary information for joining the unique wireless network; and since each network has a unique identifier, multiple wireless networks can operate in the same vicinity. If desired, sensors can switch networks through repeating the linking process with the new wireless network’s controller. The straightforward steps to linking sensors are below:
- Connect the MeshNet Controller to the network and power.
- Locate the MeshNet controller on the network by either:
- Downloading and running EDS Scanner, or
- Checking the DHCP Server for the assigned IP Address.
- From the MeshNet Controller's home page select "System Configuration>Devices". The device page will enable you to link and unlink sensors from the MeshNet Controller.
- You will be prompted for login credentials. The defaults are User Name "admin" and Password "eds".
- Insert batteries into the sensor. The sensor will appear in the "Unlinked Devices" section.
- Select the sensor when it appears and then click "OK" on the pop-up prompt.
The sensor will be linked (and moved to the "Linked Devices" section) on its next transmission.
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 EDS Temperature Sensor's alarm functions can operate independently of the MeshNet Controller the sensor can be used as a standalone Thermostat.
- 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.
