Kitchen hood controller on STM8S and touch sensing library
Good afternoon. I am now working on developing the controller kitchen hood . Here’s the final version .
It developed on the STM8S controller using touch sensing library. Springs are used as sensors. They are pressed to the glass 5mm panel that covers the outside of the device. Spring is a variant of the sensor from AN2869 Application note Guidelines for designing touch sensing applications. The principle of the measurement capacitance sensor relative to the ground , when approaching finger capacitance will vary. Threshold is set programmatically
The power supply and motor control relays.
Assembled PCB’s
The device is equipped with control terminals for 3-speed asynchronous electric power up to 200W . Also it has additional lighting control terminals with total power of up to 60W .
The main product features are:
- Adjustment the speed of rotation of the motor
- Timer
- Lighting control
Basic specifications:
Voltage, ………………………………………………………………… 220-230
Frequency, Hz …………………………………………………………50
Number of operating modes ……………………………………..3
Rated power , W:
Electric motors ………………………………………………………. 190 -260
Lamps lighting ( halogen) W . …………………………………. 60
