Sound Sensor (High Sensitivity) pulse oximeter Operation Temperature: -20 to +40

Operation Temperature: -20 to +40 °C

and GPIO for easy connectivity

The brass body is gold plated

compatible  with servo motor  to allow  rotational movement for the ultrasonic sensor

This make it good choice for making flexible sensors

Sound Sensor (High Sensitivity) pulse oximeter Operation Temperature: -20 to +40Sound sensor module with analog and digital output. It works with supply voltage from 3. 3 V to 5. 3 V. It allows you to detect not only the volume of the sound but also the identification of characteristic sound source, therefore you can distinguish the source of the sound. Besides GND and 5V input, there is a pin named "A" which can output a analog value, and a pin named "D" which can output a digital value (0 or 1). The gain which can be set by the
