NRF24L01 2.4GHz Wireless Transceiver 74HC147 we get the red light

we get the red light intensity

allowing it to give accurate results independent of the target’s color and surface

The LM35 does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room and ±¾°C over a full -55 to +150°C temperature range

Output: Analog and Digital
