Hi everyone,
what is the type of sensor in the iVac Pro Tool Plus called? The device can be seen in this youtube video:
At the moment I am using a current transformer clamp to detect if current is flowing through an AC carrying cable. However, at the moment I have to split the wires out so I...
I would like to create an underwater fish detector - completely operating underwater (personal project)
The enclosure will be a waterproof hollow cylinder (possible material to use are: acrylic, Polycarbonate or PVC), a PCB will be sealed inside that enclosure containing the sensor (the sensor...
Hello!
I need to build a circuit with a DC output that is ON whenever the AC input is active (a.i. voltage is present at the input) ideally from as low as possible but it could be as high as 200, 250 VAC and still be acceptable but needs to survive up to 1000VAC spike and some 600VAC constant...
Hello Everyone I am working on a project in which I am interfacing ZMOD4410 with Arduino UNO. The Issue I am facing is that I am unable to read data from the sensor. To debug issue I used logic analyzer to see what kind of data is writing on the i2c bus, Here I found some strange result which I...
Hello community!
I'm new on this forum. I'm working on my heartbeat sensor (pulse sensor) that uses PPG technology, i've got some troubles to calibrate the sensor. Actually, i don't know how to choose a "threshold value" in order to have the shape of that ppg signal when i put my finger on it...
Hey all, Hope you're all well.
I've been looking over the past few days for a specific type of IR Laser detector system I require for a design project underway.
To explain quickly what I need is basically a system (as small as possible) that can detect an IR laser (in multiple wavelengths)...
Hello everyone, I want to ask a question about TMP100.
The main chip I used is msp430f413. I used the emulator to check the value of the register and read it in 8 times, which are 0x0001,0x0003,0x0007,0x000F,0x001F,0x003F,0x007F,0x00FF
What degree is this? ? Is TMP100 not working at all? ...
The MPX10 series silicon piezoresistive pressure sensors provide a very accurate and linear voltage output, directly proportional to the applied pressure. Wheas, the MPX10DP is a dual-port uncompensated silicon Pressure Sensor for environmental control systems and level indicators. Come and see...
Hi,
I would like to read a sensor (acs712) a number of times (20), add them all up, then divide them by the number of reads. So I can get an average. to give me a sort of analogue "debounce". Am I guessing the sum function? I sincerely appreciate any advice you can all give me, I'm incredibly...
Hi,
I recently bought a cheap hot air gun rework station. Maybe Chinese clone of 858D. I recently knew that the 858D is one of the popular rework station around the world.
Just using it few hours, now shows "732" or "733" few seconds then shows "H-E"or "S-E". Device is not working. Sometime it...
Hi! I am trying to establish a SPI communication with an LIS2DE12 accelerometer. First, I would like to say that I have checked phase, polarity, msbFirst and CS. I am using an EM9304 as the master of the communication, and the spi clock frequency is aproppriated.
Writing or reading from the...
Hello!
The tfmini is an IR lidar sensor. There is a UART and an I2C version, quite at the same price.
For my project, I need 2 tfmini hooked up to an Arduino UNO with a +/- 1m cable.
I've been doing some tests with 2 tfmini UART versions and it works fine following the example...
Hi
I need help to boost low pulse to high.
I have a sensor which detects no of pulses per second.
For some vehicle it couldn't detect it is a low pulse signal.
Please suggest some circuite which can boost the signal.
I'm designing a tracker for assets. I want your suggestions to implement into the circuit a method to detect when someone is trying to remove the tracker. I was thinking of surrounding the board with touch pads all around the edges of the board but I guess that would be very sensitive to noise...
Hi, I'm looking for a linear displacement draw-wire, but I cannot seem to find any for purchase online. Does anyone have any links as to where to look? Been googling for a good hour, and all I can find are heavy industrial-draw wires.
I need one that has a range between 600 cm - 1 m. Thanks!
Hi!
I'm trying to build a wearable device with wifi connection, but I cant find any which is small enough to wear as a bracelet.
My objective is to use a heart beat sensor on this device, connect it to the internet and send it to my database.
Any suggestions? Right now I'm using ESP32
Hello everyone .
I am working on a project, and I stuck in one part, concerning, how to distinguish between plastic and glass, and papers if possible.
what kind of sensors can I use in this case.
thank you in advance
Hello,
I am working on a DIY project to interface a lot of signals to a NMEA2000 bus to be able to controle an older analog engine and other sensors with a new multi function display.
To do so I am using Arduino / Teensy microcontroller together with a NMEA2K library. I started to design the...
Hi guys, this is my first post here. I expect to be just the beginning. I don't have a background in electronics but completely apaixonado right now. Also, this is my first 'project' and I am here to learn. Sorry in advance by the completely dumb questions. Lets go.
First, I am looking to...
Hi all I am using the following current sensor:

Datasheet:
https://www.farnell.com/datasheets/51649.pdf?_ga=1.141388658.194281532.1473847905
I will be measuring currents in the range of 500A to -500A, and I...
Hi guys,
Lovely community here. So i got into the bandwagon of the ESP32. I am planning to build an entire data acquisition built around the ESP32. Would really appreciate it much if i were to get help from all of you. It would be a learning experience for all of us. So basically here are my...
I was pondering it would be cool to create a, lets call it a "toy" and suppose it's a bear or a doll or something, which can detect passers by and turn it's head as though it's watching them. Ok maybe it's just creepy.
Is there some kind of sensor, or way of making a sensor, which can detect...
Hello
As the title states, my ac only cheap clamp meter is reading dc currents when i am charging battery bank through an inverter...
My inverter is rated to charge 12v 150Ah battery at 16 amps and during charging when i put the clamp meter on the red battery charging cable, the meter shows...
Question for you sensor experts...
I'm looking to do a project that would involve detecting when an item passes through a doorway near ground level (~6 inches above ground level). Doing a bit of research it looks like a reflective infrared sensor would do the trick ... only issue I have come...
