ncd-red-humichip

1.0.3 • Public • Published

This library provides a class for the HumiChip, it relies on the ncd-red-comm library for communication, and includes a node-red node for the HCPA-5V-U3. The HumiChip is a capacitive polymer sensor, these chips are individually calibrated and tested, and provide high accuracy temperature and humidity readings at a low cost. Ncd.io manufactures a mini-module using this chip, allowing you to get started with no need for soldering. You can buy it here. This chip is also included in the a IoT Training Controller, along with several others, and is ideal for education applications.

HumiChip

Installation

This library can be installed with npm with the following command:

npm install ncd-red-humichip

For use in node-red, use the same command, but inside of your node-red directory (usually ~./node-red).

Usage

The test.js file included in this library contains a basic example for use. All of the available configurations are available in the node-red node through the UI.

Raspberry Pi Notes

If you intend to use this on the Raspberry Pi, you must ensure that:

  1. I2C is enabled (there are plenty of tutorials on this that differ based on the Pi version.)
  2. Node, NPM, and Node-red should be updated to the LTS versions. If you skip this step the ncd-red-comm dependency may not load properly.
