How can I make a grain moisture content sensor that can withstand high temperature? Answered
We are working on a multi-grain dryer (controlled by Arduino Mega) that dries a corn to its required moisture content (mc). If the mc is near the required (ex. 12-14%), the dryer will stop automatically. We need to make a sensor that can withstand up to 140F while the drying is ongoing. Meaning, the sensor is inside the dryer reading mc every couple of hours. If there is any device, will the reading be affected by the heat? we are pretty low on budget now so we couldn't afford to buy any pricey device and I think its hard to ship to our country in terms of period since we are pretty much running out of time for our evaluation.
