This AA boost module integrates with TI's TPS61032 auxiliary chip, which is capable of producing 5V 1A with input above 1.8V . The only difference between V1 and V2 is to change the output current from 2A to 1A.
ORP (Oxidation-Reduction Potential) is a measure of oxidation capacity and reduction of the aqueous solution. Unlike a pH measurement that follows a logarithmic curve and therefore requires more calibration adjustments, O RP follows a linear relationship and does not need any instrument adjustments as well as electrode maintenance. ORP is a reliable method of measuring water quality and provides the operator with a unique measurement value.

Now, it's time to add a more sophisticated interactive way to your project. The DFRobot touch kit comes with three types of touch sensors . A ipod styple touch wheel, a touch touch screen that supports backlit and a grid touch pad that can recognize something unique.
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>
infrared devices are widely used and often for remotely controlled devices . With this IR receiver, your Arduino project is now able to receive commands from any IR remote controller.
This sensor has a piezoelectric transducer that responds to voltage changes, generating a measurable change in output voltage that is proportional to the force of vibration . In this way, it is possible to know the vibration force , as opposed to the digital vibration sensor that only counts time.
This DTMF Shield is a Dual-tone multi-frequency signaling module decoder for Arduino With it's audio connector you can decode the crazy funny noises common phones make.
This LED Matrix 24 × 8 display is specially designed for the FireBeetle series. It supports low power mode and scroll display. With HT1632C high-performance LED driver chip , each led has an independent register, which facilitates separate driving. Integrates a 256KHz RC clock, only 5uA in low power mode, supports 16-scale PWM brightness adjustment. This product also works with another Arduino microcontroller like Arduino UNO (same as DFRduino UNO).
The MQ4 is used in gas leak detection equipment in the consumer and industrial markets, this sensor is suitable for detecting CH4 , natural gas , LNG , avoiding exposure to alcohol, kitchen smoke and cigarette smoke . Sensitivity can be adjusted by potentiometer
