WiSensys is a user-friendly, wireless system developed by Wireless Value
It collects data from a large variety of sensors used for monitoring, alarming, reporting and control.
The battery powered sensors give detailed insights in process and environmental data, making it useful for large variety of applications. The data is sent to the base station using reliable wireless communication.
The base station can be connected locally to a PC, data loggers and controllers. For this we offer a user interface on a local PC called SensorGraph. Our web based interface called Websensys allows for monitoring from any location, on any decive through Ethernet or GPRS.
The infrastructure of WiSensys starts with our range of Base Stations and Range Extenders.
Base stations receive data from up to 100 WiSensys® modules. The Range Extender acts as a repeater between sensor and base station.
The transmission range of 1000 meters (free line of sight) between the sensor and the base station can be extended with extra base stations or range extenders.
Base stations and Range Extenders can be networked to collect all measurement data.
Wireless modules with integrated sensor
Easily measure temperature and humidity with our modules with integrated sensors. We offer modules for temperature and for both temperature and humidity measurement.
We also offer battery powered modules with up to 6 temperature probes.
Modules for external temperature sensors
We have a wireless module for connecting a PT100 or PT1000 probe. Also for thermocouple type K, J or S we have a wireless module. All modules are battery operated.
Indoor air quality sensor
We offer two versions of indoor air quality sensors, measuring temperature, relative humidity and CO2.
First the WSE-DLC which has the ax+b calibration option offering the possibility to validate and justify (if necessary) the sensor on two fixed points with known calibration gases. This sensor also has the option for the single point calibration option using one fixed point with known calibration gas value.
The WSE-DLC-abc measures the outdoor air as the reference point for the sensor. It is based on the assumption that the CO2 concentration in the outside air is 400 ppm and that if a building is not occupied for 4 to 8 hours, the CO2 levels will fall to this outside level. In many applications this technology can be used such as offices, schools, homes, etc..
This sensor also has the ax+b calibration option, but not the one-point calibration.
This sensor does not allow the user to use single point calibration. This is done automatically with the outisde air (ppm = 400) as described above.
Modules for sensors with Volt/mV/mA output
There is a very wide range of sensors with Analog output. We have modules to connect:
- Sensors with 0-30V output
- Sensors with 0-4V output
- Sensors with 0-1V output
- Sensors with 0-1000mV output (process signals)
- Sensors with 0-25mA output
Wireless modules for measuring energy
Energy monitoring is becoming more and more important. Our modules connect to energy sensors by reading the pulses. The modules can be applied to230v systems, high voltage, high current and 3 phase electric systems.
Measuring energy via a power socket is also possible. Our wireless module measures the energy usage of any device plugged into a 230V power socket.
Wireless module for status monitoring like open/close, pulses and potentiometers
With status monitoring we can detect whether doors are opened or closed and measure contact change and change interval. We also measure pulse counters at a maximum of 10 pulses per second.
Potentiometers can also be connected to our platform. The output of a potentiometer is displayed in % of the full scale.
Wireless modules for connecting sensors with SDI12 protocol, sensors with MODBUS protocol or sensors with ASCII over RS232 protocol
We can also connect sensors with special protocols. For example SDI12 and Modbus sensors can be connected to our wireless module.
