Simple on-off fluid control: adds useful value when choosing parts for a build
5V Working Current <8 mA Idle Current ~5 mA Probe Frequency 40 kHz Maximum Range 600 cm (6 m) Minimum Range 20 cm Accuracy ±1 cm Resolution 1 mm Measuring Angle 75° Interface TRIG (input) + ECHO (output) — digital GPIO
The infrared receiver is hardware that sends information from an infrared remote control to another device by receiving and decoding signals
so it can be programmed and powered through a USB connection

Audio Analyzer MSGEQ7 uno r3 case Simple on-off fluid control: adds7 Band Audio Spectrum Analyzer MSGEQ7 Module The MSGEQ7 Audio Analyzer splits an audio signal into 7 frequency bands (63 Hz, 160 Hz, 400 Hz, 1 kHz, 2. 5 kHz, 6. 25 kHz, 16 kHz) and outputs the amplitude of each band as an analog voltage. Feed the output into an Arduino or ESP32 to build music visualizers, LED spectrum displays, VU meters, and reactive lighting installations.
