the energy saving technology mvioom Multifunction Sensors cnsors & D In addition to the energy vectors the Electrex monitoring and control solutions may include also environmental parameters. One way to integrate these parameters is by adding to the same monitoring system one or more sensors from the one provided by Electrex (and listed in this datasheet). The sensors may be connected in an Rs485 network (Deca Sensor RS485 or RS485 Node Box SI with Sensor Bus); or via the wireless protocol E-Wi 2.4 Ghz (based on the IEEE802.15 .4 standard) or E-Wi at 868MHz; or connected to the Ethernet / Wi-Fi via Electrex devices with built-in SI module (Net series and Libra panel with built-in SI module). Depending on the type of connection / sensor used it is possible to measure one or more parameters such as: ambient temperature, temperature on contact (e.g. PV panels, in-out boiler's water temperature), relative humidity, luminosity, pressure, differential pressure as well as count the impulses from energy, gas, water, etc. meters. The variety of sensors allow to set up applications for indoor/outdoor environmental parameters monitoring in the residential, commercial and industrial sectors. While in Energy Automation applications the sensors can be used for remote controlling, alarm and notification management and building automation. Built-in and external sensors Some of the devices are equipped with built-in, one or more, sensors (Deca Sensor RS485, Deca Sensor E-Wi 2.4 and Deca Sensor E-Wi 868); while more frequently the sensors are external (the Net series with built-in SI module, the RS485 Node 12Vdc SI and the Libra net and Lyra net SI panel). There are also devices that have both built-in and external sensors (the TE Bus versions of the Deca Sensor RS485 and Deca Sensor E-Wi 2.4). Indoor and outdoor models DECA SENSOR_ The multifunction sensors Deca Sensor E-Wi and RS485 are suitable for indoor and outdoor (if appropriately protected). The Deca Sensor RS485 4DI TE BUS and Deca Sensor E-Wi 2.4 4DI TE BUS multifunctional sensors versions are equipped with: - 4 Digital Inputs (4DI) suitable for counting impulses coming from electrical energy, gas and water meters / counters (see paragraph for RS485 version); - 1 Input for an external temperature probe (TE) measuring for example the temperature on contact of a PV panel; -1 I2C BUS to connect multiple sensors with various combinations (eg up to 8 parameters between temperature and relative humidity or 1 for temperature, 1 for relative humidity, 1 for brightness and 1 for air pressure). Alternatively, only one sensor can be connected to the bus for the detection of carbon dioxide (CO2). In addition to the versions with 4 digital input are available also versions with 2DI and 2DO or 4DO: - 2 Digital Inputs (2DI) can be used for counting (see here below for RS485 versions), while the 2 (2DO) or the 4 (4DO) digital outputs can be used for alarm states rated at 27 Vdc 27 mA compliant with DIN 43864 (available also in the 7 Vdc 30 mA versions). Only for in the RS485 versions with 2 (2DI) or 4 (4DI) digital inputs, the inputs, in addition to the counting task, can be configured (hardware modification) as state indicators (e.g. ON/OFF status of machines, switches, etc.).

Deca Sensor E-Wi 2.4 advanced settings_ The Deca Sensor E-Wi Battery, in order to make the battery last longer, uses a communication method which alternates periods of "sleep" and periods of "wake up" lasting the needed time to make the measures and transmit the data. The time between the two "wake up" periods is called ‘rendez-vous’ interval. The 'rendez-vous'...

The Deca Coordinator RS485 E-Wi 868 12Vdc is a device that can be connected in RS485 subnet to a Gateway datalogger of the Net families (Libra net, Kilo net, Exa net, Femto ECT net, Lyra net, etc.). It is the coordinator of the wireless network on the frequency of 868MHz (Wireless) managing 'end devices' such as the multifunction sensors Deca Sensor E-Wi 868 tH, which transmit the measurements of temperature and relative humidity via radio at 868MHz using the E - Wi protocol.

Advanced Deca Sensor E-Wi 868 configurations Deca Coordinator E-Wi 868 T H features To make the battery last longer in the Deca Sensor E-Wi 868 TH, the "low energy" mode is used, which is a communication technique that alternates periods in which the Deca Sensor “falls asleep” to consume less, then it “wakes up” for the period necessary to measure and transmit the measure and then goes back “to sleep”. The period between an awakening and the next one is called in the technical term "rendez vous" interval. It is possible to select the rende zvous interval between 1 minute and 24 hours, for example...
