MMM-Temperature/Humidity Module (DHT11, DHT22 and AM2302 sensors.)

psk

Temperature and Humidity monitoring Module for MagicMirror2 that works for DHT11, DHT22 and AM2302 sensors.
Dependancy : rpi-dht-sensor
For some reason, the module requires elevated permissions to run.(sudo npm start).

It would be great if someone could help in this regard.

Hope it comes of use to somebody else.

Cheers.

What is the brand and perhaps part number you’re using for this? Wiring?

@psk Do you need to run magicmirror as root?

I try to find a solution to do the same as pi

Jopyth

@Bangee As far as I know, the normal pi user has sudo rights already. I use a module to shutdown the mirror which needs sudo rights, but works fine with exec from a normal node_helper.

Bangee

@Jopyth yes, he has, but he’s going to start the MagicMirror with sudo npm start

for security reasons I try to run everything without sudo commands.

@cowboysdude DHT11 - This is the sensor that I am using.

It has three pins -
+ve - Connected to 5v
-ve - Ground
Data - Connected to pin 2

@Bangee Now, I am running as sudo npm start. Without sudo, it will throw an exception that says it cannot open dev/mem

This is the module screenshot.

I’m using node-dht-sensor

As user pi I don’t have an error but after starting MagicMirror thers a crash.

@psk you should cool down your room

I really do like this! Great job!
