Question

How many types of sensors are there in resistive touch sensor?

(a) 2 types

(b) 3 types

(c) 4 types

(d) 5 types

I got this question in a national level competition.

Asked question is from Touch Sensor in section Sensors of IOT

Answer 1

The correct answer is (b) 3 types

The explanation is: There are three types of resistive touch sensors: 4-wire, 5-wire, 8-wire.

4-wire resistive touch sensor is most cost effective. 5-wire resistive touch sensors are most durable. 8-wire resistive touch sensor, each edge of the sensor provides a sensing line.
