The SL400 is a wireless environmental monitoring system for measuring temperature and relative humidity and transmitting the readings back to a central location. The new spYdaq is a low cost wireless monitoring solution for systems with a small number of transmitters and limited range.

SL400 - Temperature e Humidity
The SL400 system is a radio based wireless telemetry system. Ideal for retro fitting a monitoring system into an existing installation with minimum downtime and cost. The SL400 system comprises of remote radio transmitters that measure temperature, relative humidity, low differential pressure, mA or voltage signals and periodically transmits the values back to a receiving base station. The radio transmitters operate on the worldwide, license free frequency and have an output power of only 10mW which does not interfere with other sensitive electronic equipment but allows up to 1000m transmission range. The SL400 base stations can now be supplied with Ethernet connectivity. This means that there is no longer a restriction on the distance from the transmitters to the base station. The software supports up to 20 base stations.

spYdaq - Low Cost Wireless Monitoring Solutions
spYdaq® is a system comprising of a number of radio transmitting sensors that measure parameters and send them securely by using a licence free radio network to a central Basestation. The data are sent using a Manchester Encoded error correcting code with multiple transmissions which, when combined with Antenna Diversity, ensures there is no loss of data in normal use from a properly installed system. Up to 16 transmitters can communicate to a single base station with each transmitter capable of having up to three inputs: Temperature, Relative Humidity or Universal - Universal inputs can be configured to accept almost any type of measurement sensor. The base station collects the data from the transmitters and connects via an RS232 serial port configured as a Modbus slave to our spYview software or any other Modbus master. The Basestation checks locally for alarm conditions with inbuilt audio and visual alarms as well as providing a switched contact output that can be used to trigger external devices. Alarming locally means that potential trouble spots can be quickly detected and corrective action taken immediately, perhaps saving an entire batch from damage.
  Power Battery / Mains: 10-28VDC; Supplied with 100/239VAC mains adaptor
Ports: USB for configuration and RS232 Modbus slave
