... interesting, the drop in sensor is reading stable, when plugged into 3.3V from the Rpi.
not sure if it's because the Sensor is on 3.3 v or if it is because the MCP3008 is on 3.3.
Even though the MCP3008 is suppose to handle 5V... i was not getting any values from multiple sensors so swopped ADC''s out and patched back into 3.3V and got this one working...
Is it not supported to run the MCP on say 3.3 for VCC and vRef.
Run 5V to sensor as input, with a 0-3.3v output ?
