Do you have a project that requires current sensing, running off a battery and want to know how much mAh battery pack you want to order? This product will essentially help inform you of your current consumption to whatever device you interface with this board with. This product uses a MAX471 Op-Amp to detect current, the MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. This device typically operates from 3V to 36V, and draws less than 100µA while idle. The module is also supplied with 2 screw terminal and 0.1" pitch headers (requires soldering).

The following module allows you to measure the current of a circuit by outputting an analog value you can then send to a microcontroller board (Arduino). Connect your inputs appropriately and for every amp measured, the board will output a volt (ratio is 1V/A, max of 3 A). To get the module working, you must first connect the RS+ pin to your positive supply line, your RS- to your loads positive end and GND to a common ground plain (as if you were connecting an ammeter). Now for the output terminals, simply connect the pin labeled OUT to any analog pin on your microcontroller and the GND pin to your microcontrollers ground.

The Gravity Conductivity Sensor Switch module can be used to detect if an object has electrical conductivity. Its maximum detection value is 10MΩ. It can detect not only coins, wires, metal and other good conductors, but also the human body, fruit, plants and other conductors. By touching the positive and negative terminals of the conductive switch, you can change the output state of the module. Use this to make interactive applications such as fruit pianos, musical wind chimes or interactive video game controllers so Super Mario using a bunch of bananas.

This component allows users to measure current of their circuit and will send data to the Arduino microcontroller to spit out an analog output value. This device has only three wires required to successfully interface with Arduino. Connect VCC to 5v, gnd to ground and Out to any analog pin on the Arduino. The conversion of the pin value is per 185mv/A. We have attached an Arduino code example to get it working straight out of the package.

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision. With the internal 12 bit ADC (Analog-Digital Converter), the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA.

This breakout board may well be the last current sensing solution you ever need to buy. Not only can it do the work of two multimeters, but it can do it with amazing precision and flexibility. With it you can measure high or low side DC current, the bus voltage, and have it automatically calculate the power. It can do so over impressive voltage, current, and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.
