I plan to transmit the number with those RPMs over BLE, please use proper noise reduction techniques to improve BLE transmissions

I'd be happy to help design your circuit! To get started, I'll need to ask just one key question:
Question 1:
What is the primary function of the circuit you want to design? For example, is it for signal amplification, filtering, power regulation, oscillation, or something else?
Feel free to provide any specific requirements or details, or let me know if you'd like me to make a reasonable assumption.

Great choice with the NRF52840. To further refine the design, I have one additional question:
Question 2:
Do you require electrical isolation (e.g., using an optocoupler) between the spark-sensing element and the MCU for safety and signal integrity, or should the sensor interface couple directly to the NRF52840?
Feel free to provide any specific details or let me know if you'd like me to suggest a standard approach.
Direct interface
Use optocoupler isolation
Direct coupling initially
