Buy on Amazon Find on eBay

The ADS1115 16-bit AD conversion module can accurately collect and convert analog signals. Through this AD module, the Raspberry Pi main control board can be very conveniently compatible with the Arduino series of analog sensors, measure various signals, and perceive this world.

Raspberry Pi is a common main control board with powerful functions. However, the pins of the Raspberry Pi main control board can only read digital signals. If you need to read the signals of analog sensors or devices, you can only connect an analog-to-digital conversion (ADC) module, which is not convenient to use.

This module uses the 16-bit ADC chip ADS1115, which supports a wide voltage supply from 3.3V to 5V. The chip has a precision reference voltage and programmable gain adjustment (PGA), so it can be used for weak signals or signals with large changes. Accurate acquisition and conversion, so this module is also suitable for all kinds of occasions where the main control board needs to accurately collect analog signals.

One AD module can read 4 channels of analog signals. Due to the onboard I2C address selection switch, it supports the cascade of 2 AD modules and reads 8 channels of analog signals, which is sufficient to meet the needs of various scenarios.

Ocean: ADS1115 16-bit AD conversion module is specially designed for Raspberry Pi compatible with Arduino series analog sensors, which greatly reduces the difficulty of Raspberry Pi main control board compatible with Arduino series analog sensors, plug and play, no soldering, very convenient.

CQRobot Ocean: Non-Contact Water/Liquid Level Sensor Compatible with Arduino, Raspberry Pi and Other Motherboards. for Industrial Production, Aquarium, Chemical Liquid, Agriculture, Gardening, etc

Liquid Level Sensors

Buy on Amazon Find on eBay

The principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, the sensor has a certain static capacitance to the ground due to the existence of distributed capacitance on the sensor. When the liquid level slowly rises and approaches In the case of an inductor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the final capacitance value of the inductor larger.

The CQRobot non-contact liquid level sensor realizes non-contact detection of the liquid level in a closed container. It adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness. It is simple to install and easy to use, and can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers.

The sensor comes with 2 DIP switches, the right DIP switch controls the output voltage (high level) of the signal terminal (green line); when the DIP switch is dialed up, the high level is 5V; when the DIP switch is facing When dialing down, the high level is 3.3V. Compatible with Arduino, Raspberry Pi and Other Motherboards.

The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain amount It is considered that the liquid level has reached the sensing point when the threshold is reached.

High stability, high sensitivity, strong interference ability, no external electromagnetic interference, special treatment for power frequency interference and common mode interference, strong compatibility, penetration of various non-metallic containers, such as plastic, glass, For ceramics and other containers, the sensing distance can reach more than 12mm; liquid, powder, and particulate matter can be detected.

for flying toys, drones, handheld devices, such as mobile phones, tablets, GPS devices, navigation systems, portable health devices, home weather stations, watches, white goods and other application scenarios.

Note: The altitude calculated by the air pressure sensor is generally used as a relative value in a short period. For example, when taking a vertical elevator, record a height before the elevator starts, and the elevator rises to the 3rd floor, and records a height. The height difference between the two heights is accurate.

If you need to use it in absolute situations, you can enter the height of the current position as the initial value of the calculation, and then exercise to observe the height change is accurate. However, if the time is long, the problem of height drift will easily occur. If the project requires long-term acquisition of accurate altitude values and high frequency requirements, it needs to integrate other sensors for processing, such as GPS.
