The Current Sensor 70A is a great option for those looking for equipment to measure current up to 70A and that is non-invasive.

Analog Hydrogen Gas Sensor MQ8

Analog turbidity sensor for Arduino

Bi-directional Logic Level Converter 4-channel by I2C BSS138

The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.

Color is a Light to Digital Color Converter with IR Filter. The TCS3472 Device provides a digital red, green, blue (RGB) return and sharp light detection values. An infrared blocking filter, integrated in the chip and located in the color-sensing photodiodes, minimizes the infrared spectral component of the received light and allows color measurements to be made accurately.

This unit communicates with the M5Core through the Grove (I2C) port. The address is 0x29.

This version of the Ethernet Shield is not only compatible with Mega 1280 and 2560, but also provides a Micro SD card slot for read / write

DHT22 is a digital capacitive humidity sensor and humidity module is one that contains the compound has been calibrated with digital signal output from the temperature and humidity sensors . < / p>

This module is based on the popular L298N H Bridge DC Motor Driver . The circuit will allow you to easily and independently control two motors up to 2A each in both directions.

The ESP32-CAM is a WIFI + Bluetooth Development Card based on the ESP32 Chip, with the additional possibility of using a camera. It is ideal for a variety of loT applications.

This ESP8285 ESP M2 Module provides easy-to-use WiFi for any UART port and is compatible with the HC-06 Bluetooth modules. If your project uses Bluetooth, it is very easy to convert it to WiFi. Using the integrated web interface, WIFI-UART communication can be configured for TCP or UDP sockets on any port.

This is the FeatherWing Adalogger: it adds a real-time clock with battery and micro SD card storage to any Feather mainboard. Using the Headers, you can connect a FeatherWing to the top of your board and let the board fly!
