  • Opto-Isolated AC Voltage Sensor about 14 hours ago

    You can substitute a light of any size. Search for a 24V AC Pilot Light on Amazon and you will get plenty of hits. This will help you get some ideas which you can then use to source a light that fits your needs. You may need to adjust the size of the resistor with a different light.

  • DHT11 /DHT22 Temperature Sensor about 1 month ago

    Step one is to ensure you are using the DHT11 class instead of the DHT22 class. If you are using the DHT11 class already, the next thing I would check is whether this could be related to timing based on the other sensors. Since this sensor requires precise timing, it is possible that reading from the other sensors is causing the issue. Try commenting out all the other code and see I you can read the DHT11 by itself. If you can, add the sensors back one at a time and see if the DHT11 starts to fail. If by itself, it does not read, check the circuit. I also like to do a quick test with an Arduino to ensure he sensor is working. If you have any Arduino, try hooking the sensor up to that and do a quick sensor test.

    If all this still does not yield a good result, let me know. I may be able to help troubleshoot via pictures of the circuit or with access to the code.

    You may also want to check out my article titled "DHT Tiny Breakout for the Raspberry Pi" for an alternative. This is a little more complex and requires an ATtiny85 chip, but yields perfect readings every time.

  • DHT11 /DHT22 Temperature Sensor about 1 month ago

    Which sensor are you using (DHT11 or DHT22)? Ensure that you are using the correct class which your sensor there is a separate class for the DHT11 and DHT22). Also, if you have any type of Arduino (such as an Uno) or a compatible, a quick check on that device will help determine if the sensor is functioning properly or not.
