3/11/2017· Enable the sensors triggering function (eg: a max. temperature alert) Load register (s) with the parameter value for that trigger (eg: °C) Turn on the status register that listens to that triggering function. Map that status register bit to a hardware output line. Reenable the global interrupt control bit.

3/11/2017· REGISTERS are simply memory locations inside an I²C device. The summary of how many registers there are in a given sensor, and what they control or contain is called a register map. Most of the information on the sensor’s datasheet is about explaining how each register functions, and they can be quite a slog to read through because the information is rarely presented in an intuitive way.

Dissolved oxygen is one of the important parameters to reflect the water quality. Low dissolved oxygen in water will lead to difficulty in breathing for aquatic organisms, which may threaten the lives of these animals. We launched a new opensource dissolved oxygen sensor kit, …

The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a builtin potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.

24/6/2018· Amigos, Estou precisando de um detector de oxigênio no ar na escala de 1 a 1000PPM. Eu conheço os do tipo FIGARO, más a resposta deles são entre 200 e 15000PP…

23/6/2020· Overview: In this project we will be “interfacing HX711 Load cell amplifier with Arduino” and 16*2 LCD for designing Weighing Machine using Arduino Load Cell HX711 Module. This is a simple “Arduino Weight Measurement project”.. The electronic weighing machine uses a load cell to measure the weight produced by the load, here most load cells are following the method of a strain gauge ...

Overview. The Arduino Mega is a microcontroller board based on the ATmega1280 ().It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a ...

28/10/2019· The difference between analog and digital sensors is that an analog sensor collects readings over a range of values, and a digital sensor only reads a HIGH or LOW signal (a bit of data). The Arduino has a 10bit AnalogtoDigitalConverter (ADC), which maps sensor readings between 0 and the operating voltage (5V or ) into integer values between 0 and 1023.
