5 FAQ

Q: Does it work with 3.3V logic?

A: Yes, it is compatible with both 3.3V and 5V logic systems.

Q: What resistor value do you recommend?

A: We recommend a 10k ohm pull-down resistor for general purposes.

Q: Is this waterproof?

A: No, this is a thin-film sensor and should be kept dry.

Q: Can I connect this directly to a microcontroller?

A: You need a pull-down resistor to convert resistance to voltage for ADC reading.

Q: Can I cut the sensor to size?

A: No, cutting the active area will damage the circuit and void functionality.
