Grove sensor with Raspberry PI and Node Red

Post by morezz78 » Mon Sep 16, 2019 5:37 am

Hi,

I bought a Grove - Solid State Relay V2 SKU 103020137 and a Grove - High Temperature Sensor SKU 111020002 and I'm trying to use them on a Raspberry PI with Grove - Base Hat for Raspberry Pi writing the program with Node Red. It seems that is not working.

Can anyone confirm me that both sensors can work connected with a Grove Base hat and Node Red?

Bet regards
Matteo

Hi Matteo~

Grove - Solid State Relay V2 SKU 103020137 is a digital sensor, work voltage is 5v. The Grove base hat for raspberry pi is 3.3v. From hardware point of view, It is not compatiable.

Grove - High Temperature Sensor SKU 111020002 is analog sensor, which works with 3.3v/5v. From hardware point of view, it supports the grove base hat for raspberry pi. But you have to write your owner code to make it work.

We do not use the nodered before and can not provide the related instructions. thanks for understanding.

Hi Bill,

thanks for your reply.

For the relay I'll try a different way and for the temperature sensor I'll write my own code.

Thanks
Matteo
