Max distance between spark and sensors

Hello, what is the maximum distance in meters of cable can be used between the spark and such a motion sensor or a temperature sensor or a door opening sensor?

Hi @rbbahia

This is way too broad a question to answer directly since every sensor is different.

In general one-wire sensors like the DS18B20 can be cabled up to several meters away from a host.

With other sensors like those with i2c or SPI interfaces, one meter would be quite long and could be hard to get working.

It just depends.

@rbbahia, if you can describe a specific scenario, we can help you a LOT more. The whole point of a wireless Core is to have it near the sensors and devices it interacts with. Long wires kind of defeat that purpose! :smile:
