This tiny MEMS microphone has an amplifier gain of 66. When there is no sound detected, it outputs voltage around 0.66*VCC. When speaking, you can easily get the...

The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.

This I2S digital amplifier based on the MAX98357 I2S Class D amplifier module works great with microcontrollers with I2S audio outputs like ESP32 and can...

This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class...

This current-to-voltage module can linearly convert 0~25mA current signals into 0~3V voltage signals. Industrial sensors or devices usually have the current signal output of 4~20 mA. With this current-to-voltage module, your main control board can easily attain the current signals input from industrial sensors or devices.

The Monk Makes Sensor Board for micro:bit allows you to sense sound level, temperature and light level.

A 16-bit self-calibrating analog-to-digital converter that operates on I2C

The ADC Pi is an 8 channel 17 bit analogue to digital converter designed to work with the Raspberry Pi. The ADC Pi is based on two Microchip MCP3424 A/D converters each containing 4 analogue inputs. The MCP3424 is a delta-sigma A/D converter with low noise differential inputs.
