REACH is a technology framework consisting of software and hardware components for the creation of a low energy sensor/actuator network. There is no limit to the number and type of senses that can be connected. It supports inputs like Digital, Analogue, Serial, Pulse, etc and outputs like switched output, PWM, serial, Voltage ramp, etc. It supports industry-standard sensors and actuators with a facility to integrate nonstandard ones.
In REACH, sensor/actuator modules are interconnected using any or multiples of the wired protocols like Ethernet, RS232, RS485, 4⁄20, 3 wire/4 wire compensated sensor connections, etc and wireless protocols like Wi-Fi, BLE, LoRa, GPRS, 4G, XBee, ZigBee, etc. These are optimized for low energy operation.
