sensor development

Hi i want to develop an application to track whether a person is wearing helmet while driving his motorcycle. For this i need a sensor which can be easily installed in existing helmet , Please suggest a sensor which can be used .Purpose of the sensor is just to give a notification / alert to the...

Good evening, I have a project I have in mind that uses the ESP32 to read sensors, preprocess the data and stream back the data to a host using Wifi, or Bluetooth with UDP protocol. The data are then analysed and interpreted by a software and sent back to the ESP32. I would like to use the...

Help Needed: SPI Clock Signal Stuck High on Custom PCB with 48 MLX90393 Sensors (Hall Effect Device for Palm Rehabilitation) Hello everyone, I am currently working on my master's thesis, where I am developing a hall effect-based device for palm rehabilitation. The device is designed to...

Hi all, I have some FSR 402 sensors that look like this: (Datasheet here) I also have some FCI clinchers that look like this: (LINK) Now I realized that I can add the clinchers only to a FSR without the pins. Can I trim off the end up to here: so I could add the clinchers? I would like...

I got this pH sensor board circuit design from one of the forum discussions. Can anyone please explain the significance of the resistors and capacitors used? I am new to the circuit design.

Hello guys. I'm using an efr32bg22 Bluetooth module and would like to read a thermistor with it! I've never used a thermistor. Reading a little about the subject, it seems a little complicated to me. There are some formulas for obtaining a conversion but apparently the best way is to use a...

I am looking for laser sensor to measure velocity of fast moving bullet/projectile traveling through barrel. I have a bullet of 5mm length and it would cut the laser for just 5- 20 microseconds. The sensor need to be fast enough to give trigger to oscilloscope with this kind of small intervals...

Hi, I am working on INA128 instrumental amplifiers for taking the signal from forearm muscle. I am operating on 5v single power supply to power up the INA128. I am dividing these 5v into two voltages with respect to 2.5 reference voltage(5v to 2.5v and 2.5v to 0v). The maximum rail is 5v and...
