ProMax PST16240BM Push Button Momentary Switch Round 240V Blue Indicator Light HC-05 Bluetooth Module with with TTL Output (Pack of 20) The tradeoff is slightly higher

The tradeoff is slightly higher power consumption and cost

the changing resistance produces a varying voltage that can be read by any microcontroller's analog-to-digital converter (ADC)

Type Infrared Flame / Heat Detection Sensor Module Detection Spectrum 760nm-1100nm (Near-Infrared) Detection Angle Approximately 60 degrees cone Detection Range Up to 80-100 cm (open flame) Operating Voltage 3

Its 4-wire bipolar design maximizes torque per amp by energizing the full winding in each phase

The circuit works with standard 5mm and 3mm LEDs
