Humidity Sensor Circuit. The relay is opened when the 10K resistor is connected to point A, not to point B as shown in the schematic. You can use other sensors like LDR or NTC instead of the copper ones so you can use this circuit for detecting light or temperature. Schematic of the Humidity Sensor Circuit
The Capacitive Humidity Sensor. The Capacitive Humidity Sensor – How it Works & Attributes of the Uncertainty Budget Principle of Operation T he humidity sensor is a small capacitor consisting of a hygroscopic dielectric mate - rial placed between a pair of elec - trodes. Most capacitive sensors use a plastic or polymer as the dielec - tric material, with a typical dielec - tric constant ranging from 2 to 15. When no
Direct Interface Circuit For Capacitive Humidity Sensors. This paper proposes and analyses a direct interface circuit for capacitive humidity sensors. Such a circuit relies on directly connecting the sensor to a microcontroller without using either a signal conditioner or an analogue-to-digital converter, thus resulting in a simple, compact, low-cost and low-power interface circuit. In spite of its

The curve reveals a close exponential
Circuits And Techniques For Implementing Capacitive Touch. Let’s say we have an RC circuit composed of a 1 MΩ resistor and a capacitive touch sensor with typical fingerless capacitance of 10 pF. We can use a general-purpose input/output pin (configured as an output) to charge the sensor cap up to the logic-high voltage. Next, we need the capacitor to discharge through the large resistor. It’s
