This metal detector A88 non-contact metal induction detection module can be used as a metal detector. You will hear a sound when approaching metal.
The user can configure the digital output as PWM. By default, 10-bit PWM is configured to continuously transmit measured temperatures in the range 20-120 ° C with an output resolution of 0.14 ° C.
MLX90614 ESF is an infrared thermometer for non-contact temperature measurement. Both the IR-sensitive thermopile detector chip and the signal conditioning ASIC are integrated into the same TO39 package. The integrated MLX90614GY906 is a low noise amplifier, 17-bit ADC, and powerful DSP unit that delivers the high accuracy and resolution of a thermometer.
