    How to remove noise from sensor data in python?

    Hello everyone. I have a sensor that I am continuously reading data from, at a constant rate, using python. Looking at the data there is obviously noise in it (bounces around when it should be zero or a constant value). After googling for 2 days I've not been able to find a way to remove the...

    SAW Sensor - Why is my circuit not oscillating?

    First, sorry for the bad english. It's not the first time I've been looking for help on this circuit on the forum. I'm from Brazil, I'm doing a university project using which basically consists of using a colpitts oscillator with differential pair, with a SAW sensor in its feedback loop. The SAW...

    Battery, Light sensor and a mini motor?

    First the picture, because a picture is worth a thousand words. Is this possible? If the light is OFF, then the motor stops. Low light brigthness = low motor speed. High light brigthness = high motor speed. Thanks.

    Low cost height sensor Lidar or ToF for detecting box heights on a conveyor

    Hi, I need some help in looking for a Lidar/ToF or any other height sensor for a barcode reading application. We have a machine vision camera with liquid lens whose focus can be adjusted to predefined focus planes. Now, if the height of the box is known, we can adjust the camera to the right...

    How can a BGS sensor detect colors?

    Hello, I've been searching how can a Background Supression sensor detect colors but I still can't find an answer nor understand how is this possible. From what I've read, I know this sensor can detect an object regardless of its color since it measures refraction angles and not light intensity...

    State machine design for sd card detection and logging

    I am trying to design a state machine for the logging sensor which has the following scenario : Bootloader will send the signal whether a sd card is valid or invalid. If logging sensor receives valid signal, and there are error messages present, sensor will write the data to sd card and...

    PsOC 4 BLE (pins problems)

    I am running a project using a thermistor. I started by using the evaluation board as shown: The program runs fine. After that, I removed the module from the evaluation board and powered the module using an external power source (3V). I moved the resistor and thermistor from the evaluation...

    Impact force measuring sensor

    Hi all! I dont know much about sensors or hardware in general (Im a computer science student) so I would really appreciate some help here :) I am looking for a flexible impact force sensor (for measuring a punch) , it needs to be around 10X10 cm and I want to connect it to Arduino or raspberry...

    Alternatives of break-beam sensors (one-side implementation instead of both)

    Hi, I would like to know if there's any alternatives that can replace break-beam sensors in this situation — a gate that counts how many people has passed through using a sensor implemented on one side. If there aren't any alternatives, can an ultrasonic sensor be used to replace the break-beam...

    MPU9250 and HMC5883L sensor fusion

    Hi. I’m working on a robot project and I need to get gyro, accelerometer data from MPU9250 and magnetometer data from HMC5883L then combine them. I will use arduino as a platform. Is it possible to do it? I have never used these sensors before. What are your advices for this project?

    gas flow measurement in ml/min and m/s

    I want to use gas flow meter. I checked for some sensors which have given measurement in ml/min and some has in ml/min. I tried to convert the ml/min to m/s on google but got the result in m3/s. I am not sure about the flow measurement and units used in the datasheets. Is there any explanation...

    Dielectric permittivity measurement of solid materials using capacitors

    Hi, I am currently doing some research work on different ways to measure permittivity of materials. In particular, I want to measure the permittivity of FR4 materials of PCB, and of an aluminium oxide block of approximately 0.5 cm^3, at 2.45 GHz. One idea I want to explore is how to measure...

    BNO085 - Bringup

    Hello, I tried to breakout the BNO085. I used a known good design from Adafruit (attached the schematic). Now unfortunately it doesn't work. I written software for the Adafruit board and it works fine. Then I replaced the Adafruit board with my breakout board ("schematic_not working" in the...
