This is a quick project I put together to explore using small-size IoT modules for practical work, say Health & Safety or Equipment monitoring and reporting. For this post I’ll use the super-compact Cactus Rev 2 which gives me multiple I/O ports with WiFi built-in via an ESP8266 and I will use that to transmit three sensor values to Dynamics AX 7 via ThingSpeak.


The Cactus Rev 2 module is an amazing little device that measures less than 4cm by 2cm and is half a centimeter thick. It can be powered via USB or RAW and runs off
