SCALAE WIFI SWITCH is an WIFI enabled monitoring system that is configurable and versatile. As a PIC Microcontroller based embedded system, it is low cost and adaptable to multiple applications. Supporting cost effective and standardised technology, the unit uses existing infrastructure to tie in for data reporting event notifications. Reporting is via WIFI or GSM* depending on requirements.

* Compatiable GSM module is currently under development.

Usage and Integration
SCALAE WIFI SWITCH is designed to integrate with an existing or new cold storage implementations. The unit is compact, low power and couples seamlessly with existiing infrastructure for power and communication requirements. Designed for cost effectiveness in mind, the unit is highly competive in features and capabilities.
Display Applications
Embedded applications range from standalone systems which control a single element, to wired or wireless applications interconnected for reporting and monitoring. As a control NODE is an ideal, cost effective and well supported tool with an efficient tool chain that will assist in completing projects and getting products to market.
Temperature Sensor
SCALAE - CRYOS offers the selection of 3 different types of sensors. The unit is preprogrammed to function with either of them. You have the choice of:
  • LM35
  • Dallas 1 wire 1B20
  • DHT-11

Opto Inputs & Relay Out

The Opto-Coupled inputs isolate Cryos's low voltage control circuitry from the outside world. The allows the unit to be integrated with high voltage systems and work with high voltage input signals safely. Two configurable inputs are available.
The unit includes a relay which allows the unit to switch a high voltage load, or to be integrated with an adjacent system to do the same.
The module offers a number of methods for wireless integration. The following are currently available:
  • ESP8266
  • GSM Modem*
The wireless module is housed inside the din-rail enclosure, operating on the interal power supply.
Real time Data Display
The system offers the opton of an integrated display, which will report the temperature locally for display at the unit.
