In this guide, we’ll be attaching an XTP25N-030-0300F Temperature Sensor to an Avimesa 1000 for temperature monitoring via Avimesa.Live. The XTP25N-030-0300F Temperature Sensor is a type of sensor known as a 4-20 mA current loop sensor (420 sensor for short). 420 sensors are used heavily…
This tutorial is intended for a RaspberryPi and will show how easy it is to integrate Avimesa Gadget with Node.JS and some temperature sensors. We will be using the child_process npm module to control Gadget. The temperature sensor being used is a DHT11/DHT22/AM2302. We will…
This is an excerpt.

Curious about what a 4-20 mA sensor is or how it works? Let’s run through what a 4-20mA industrial sensor is and how a current loop is used to output data.
