I've run into an issue using the Phidget22 API (Python 2.7) setSensorType method. It works ok for me, but I have found I need a half-second sleep delay after using it before I can use a getSensorValue. Without a delay I get a "Phidget Exception 51: Unknown or Invalid Value" error. It does ...

I'm not familiar with the 1051 Temperature sensor, but you might have to set the ThermocoupleType before calling the getTemperature method?

You need to give it time to attach before trying to call it. You could just put a sleep(1) after your open, but that would be inefficient, especially if opening a lot of devices. Better to replace your open() with openWaitForAttachment(5000) if going for basic or even better use events if going for ...

Thanks, I think I got it. I shouldn't use getSensorValue without first setting the sensor type to 0x2be8 (11240) in the case of my 1124 temp sensors. I tried that and do indeed get back the temp in degrees Celsius. I also tried applying a formula to the VoltageRatio itself by working backward from w...

Here's a simple test program that illustrates my issue. For this test, I'm using an 1109 Rotation Sensor (pot) instead of a temp sensor. As I rotate the pot, the VoltageRatio changes while the SensorValue remains the same as its initial reading. from time import sleep from Phidget22.Phidget import *...

I have a Python program I've been using for years to monitor my home heating system. At one time or another I've used it under both Linux and Windows. The Phidget hardware consists of a 1018-1 interface board and (6) 1124 temperature sensors. At the heart of the program it polls all the temperature ...

The hardware for my current home heating system and environment monitor consists of a Phidgets 8/8/8 Interface connected to a Beagleboard xM single board computer. The Beagleboard is running Ubuntu 16.04 Linux headless. It is accessible on my home network from computers running Windows 10. At presen...
