Sensebender Micro & External Sensors (ds18b20)
-
Hello all,
I'm succesfully using some Sensebender boards with 2 AA rechargeable batteries each, and I'm very pleased about the function and battery lifetime. It's very far beyond my expectations!
But until now, I only used the internal temperature sensor. Now I want to use an external sensor (because the signal quality out of my fridge is really bad), an ds18b20 for example.
I'm wondering if that's possible since the sensor has a voltage minimum around 3 Volts, and my batteries supply at most 2.6V.
Any experiences out there? Or some hints for me? What can I do?
Regards,
Marcus.

Get a sensor that supports lower voltages or get a step-up.
