    Reading from 4 identical sensors using a Raspberry Pi...

    Thanks very much! Yes I had worried about the start up time of the sensors. So, I'll look at FET switching devices to switch between the I2C lines? whilst keeping all the sensors powered continuously? Thanks again.

    Reading from 4 identical sensors using a Raspberry Pi...

    Had an idea this evening that I could just use the 4 output (5v tolerant) pins (which sink to ground when ON) to cycle power each sensor. Initial tests showed that if I wired a sensor to SDA and SCL and 5v in, with the GND set to one of the output pins then yes - when the output pin was set to...

    Reading from 4 identical sensors using a Raspberry Pi...

    Hi, total electronics noob here. Am slowly teaching myself the basics but current project dictates that i must run before I can walk! I have 4 proximity sensors (VCNL4010) that can be controlled using I2C. However, they are have the same address and the address cannot be changed. The Pi only...
