Hi, I am a newbie here. I have worked with node-red that has already installed sensors or I got npm install files from the internet.
But now I want to work with [this temp and hum sensor](https://store.ncd.io/product/sht31-humidity-and-temperature-sensor-%c2%b12rh-%c2%b10-3c-i2c-mini-module/) and send its data to google sheet using node-red.
But, how can I add this sensor in node-red?
Any leads will be a great help.
Thanx in advance.

How do you read the data coming from the sensor ?

Its an I2c device so you could use [https://flows.nodered.org/node/node-red-contrib-i2c](https://flows.nodered.org/node/node-red-contrib-i2c) to get data from it.
Unfortunately, this is going to require a bit of prodding and poking to get it working
This should give an idea of commands needed and format of received messages

PS You can proably get the module in a cheaper configuration

Hi Adam, I’m a bit late to the conversation. Have you followed NCD’s own Node-RED tutorial for connecting these sensors to Node-RED yet? For connecting it to a google spreadsheet there’s countless of questions on this forum, a search should find you a solution that works. But start with NCD’s tutorial, it gives you the basics.

I just published a first version of a node for the SHT31...
[SHT31 Contrib Module](https://flows.nodered.org/node/node-red-contrib-sht31)
it's barely tested, but it works for my custom setup... any feedback welcome...
