Sensors

Water is essential for life on Earth. Using water efficiently is very important. With the easy-to-use simple rain sensor, farmers can save water while irrigating their crops. The sensor will alert them to shut down the water supply when it senses rain. It can even act as an automatic on and off switch, like turning on wipers on a car when it senses rain.

This sensor has two pieces – the rain sensor and the simple sensor. The rain sensor has nickel-coated lines on both sides. It measures moisture and outputs the data to the simple sensor that reads it. The simple sensor uses the LM393 differential comparator. The main benefit of this board is ability to give analog and digital output. By setting the potentiometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

Fuel gauge is a special type of accessory for lithium batteries that very precisely measures the state of the battery. This includes current voltage [mV], state of charge [%] and probably most interestingly: remaining capacity in the battery [mAh]. It is used with 1S batteries, and provides all this information via the I2C interface.

On our board you can find easyC connectors which allow I2C communication with microcontroller. Also, there is a JST input for any pouch battery you can find in our offer, as well as quick connect terminal connector for input if your source doesn’t have JST connector.

It sends all this data via I2C communication, which is easy to read via our Arduino library.

Ever wanted to build your own weather station using Arduino? Then the BMP180 breakout board with precision sensor from Bosch might interest you. The digital sensor on the board precisely measures the changes in barometric pressure and temperature. It uses the piezoresistive effect to gather the information. Since the pressure varies depending on height, the sensor can measure altitude too. Very low current consumption and voltage allow this type of sensor to be used in many modern devices.

The design is 5V ready with an onboard regulator for 3.3V. The breakout board’s standard current consumption is very low, only 5 µA. It uses an I2C interface, and the I2C address is 0x77. No soldering, nor need for distinguishing between SDA and SCL is required due to easyC. The sensor has integrated EEPROM memory with data for calibration. The pressure is measured in steps of 1hPa (=0.01hPa =0,01mbar), and 0.1°C for temperature.

Product usage tips:

If there is an error while using the breakout board, see if it’s connected properly. Take a look at the pinout. If everything is properly connected, check if the I2C address of the breakout board is correct prior to programming it. The I2C 7-bit address should be 0x77. If everything is correctly connected and the I2C address is right, look through your code once again. There might be some bugs in the code that are stopping the sensor from working as it should.

BMP180 breakout board works very well in combination with any Dasduino board and OLED I2C 0.96” display breakout board. All of them use easyC so they can be connected in a matter of seconds. The BMP180 sensor can measure the barometric pressure and temperature, while the OLED display can show them. The breakout board also comes with two mounting holes so you can attach it onto something and it won’t budge.

To keep the sensor working for a long while, we would advise you not to use it in extreme conditions. Going over or below the temperature range will surely damage the sensor. Same with the pressure. Keep track of the current going through it. Allowing too high of a current through the breakout board will burn the sensor and render it completely useless.

To keep the longevity of the sensor, keep track of the current going through the circuit. Allowing an excessive amount of current to flow through it may cause the sensor to fail. It is not impact-resistant. When dropped from a high distance or at an odd angle, it can break beyond repair.

The Hall effect sensor breakout with analog output is a versatile and reliable sensor module designed to detect and measure magnetic fields. It utilizes the Hall effect principle, where the presence of a magnetic field induces a voltage proportional to the strength and direction of the field.

This sensor module features an analog output, which provides a continuous voltage signal that varies in response to changes in the magnetic field. The analog output allows for precise and real-time monitoring of magnetic field strength. It is commonly used in applications such as position sensing, current sensing, and speed detection.

The module is typically powered with a supply voltage ranging from 2.25V to 5V, making it compatible with a wide range of systems.

The hall effect sensor (Hall Effect sensor) will be able to detect the magnetic field in its vicinity thanks to the aforementioned physical law. A magnetic field that can be created by a magnet, a current flowing through a conductor or some third source, the Hall effect sensor will recognize each. The stronger the magnetic field, the higher the voltage will be at the output of this sensor, so it is a sensor with analog output.

Due to the jumpers on the board, the I2C address of a device can be changed. Thus, eight breakout boards can be connected to a microcontroller. All of the pins on the expander board have pull-out resistors that can be turned on and off.

The HX711 is a highly versatile load cell amplifier that is widely used in various applications requiring precise weight measurements. It is designed to convert analog signals into digital values, making it ideal for integration with microcontrollers, Dasduino boards, and other digital systems.

This load cell amplifier employs a 24-bit analog-to-digital converter (ADC) to ensure high-resolution and accurate readings. It supports differential input signals and offers two differential input channels, allowing the connection of up to two load cells simultaneously. This feature enables the measurement of both single- and multi-load cell systems, expanding its application range.

The HX711 incorporates an integrated voltage regulator, which provides a stable supply voltage for the load cells and ensures accurate and reliable measurements. It operates with a low supply voltage, typically ranging from 2.6V to 5.5V, making it compatible with a wide range of power sources. This breakout board features connectors for easy connection with other boards and microcontrollers within the easyC system. It also comes with switches for selecting the I2C address.

The HX711 breakout allows you to easily read the weight value from a load-cell sensor (mass sensor). This small ADC is of great precision and is capable of measuring very small changes in the load-cell resistance, whose signals are amplified with the built-in amplifier. Subsequently, this same information is digitally transmitted to a microcontroller that simply converts the numbers obtained into the actual weight. That’s why this breakout is very useful for projects with scales or presence sensors, either for individuals or industry.

Breakout supports the connection of load cells that are made by the Wheatstone Bridge technique, like most of the load cells. They usually have four wires, two for power supply (E + and E, most often red and black), and two for signal (A + and A-, most commonly white and green wire). The pins for these wires are also indicated on the PCB and it is easy to connect.

The TCRT5000 is an infrared (IR) reflective sensor module that is commonly used for proximity sensing and line-following applications.
