Hi all: I am in the process of designing a project for school. This project requires a GPS sensor and a barometric pressure sensor to determine position in space. I have not much knowledge about sensors yet but I am trying. I have spent several hours googling a few terms and so far I came up with the Garmin 18 GPS sensor, and I am still not sure which barometric pressure sensor I will u...

Hi Group, I intend to make a weight aqcuistion digital system. For the sensor I bought commercial digital scale that have range 0-5kg with 1gr resolution. (TANITA KD-403) After I opened the casing, I found that the load sensor and the processor connected by 4 wire: V+, V-, S+, and S- (this written on the pcb). I guessed that the sensor is strain gauge with bridge. So I did some research...

Hello, I'm new in this group, and I hope this is the right one to place my question. I am trying to connect a tilt sensor to a pc. The sensor device (Analog Devices' ADIS16201) is accessable via spi. Unfotunately, I'm not very conversant with programming Micros not even with programming serial communication. But since SPI is such a simple protocol I tried it using FTDI's FT2232C. That did no...

I'm trying to implement an OV7620 sensor on a Spartan 3 (Xilinx FPGA) to display on VGA, the problem is to syncronize the sensor data with VGA exit. The sensor is already programed to send data in progressive mode by 2 channels: channel Y G G G G channel UV B R B R Please, somebody can tell me how to syncronize with a monitor to display data on VGA? Regards!!!

Hello, I have limited experience with microcontrollers, all with freescale HC12 and HCS12 systems. I have dealt with 0-5V sensors through ADC before, too. I currently have a project where I might have to use a 4-20mA sensor. How would I go about electrically interfacing a 4-20mA sensor to a generic microcontroller? How would you power it and read it? Is there an IC available? Any suggest...

Hi, I have been searching the web for a low cost image sensor. The application is for reading a type of barcode, approximately 20mm x 5mm, but I could make do with an area as small as 10mm x 3mm. A resolution of 0.1mm would be more than adequate, and I only require monochrome. Ideally I would like no moving parts, and no lens. The item to be scanned would be placed directly on the sensor, il...

Hi, I' m looking for solutions to interface a 1.3Mpixels CMOS image sensor, I' ve thought to use a FPGA but it seems to be a little expensive. What about the market? Is there dedicated circuits to realize the interface and stock the data? Is there processors with DMA transfert which allow to interface the sensor? Thanks for your help.

Lots of questions, I hope someone can guide me in the right direction! I'm looking for some help in designing a system that can take data from an image sensor and store it in some sort of MMC/flash memory. It will be part of a wearable device for monitoring diet/activity constantly during the day. We're looking into using an image sensor from OmniVision that has built-in JPEG compression (e...

Hallo there Hi, I want to carry a research project on a sensor that can suitable to Detect an stable object. I would like to get an idea on how i can implement my project. I want to implement a sensor which can emit a ray or any kind of non hazadous emision which will respond to an object in a distance of one meter 1m then send the feedback to a board to produce an oscillating signal hence the ...

I've been given a sample Honeywell capacitative proximity sensor by a client. He wants me to build a small micro-based project to interface with it. The sensor is shipped in a bag labeled "992AA12AN-A2", and the documentation for "992 series" sensors consists of four letter-sized sides, most of which are multilingual translations of warnings and mechanical specs. The electrical documentation ...

Hi, I am currently working on a university project that concerns the functionality of an inductive loop sensor. While I understand its basic functionality I am unsure how to use it with microcontroller. We will be using the sensor to detect vehicles that are parked in a parking spot. Once detected, we want the sensor to communicate with some sort of microcontroller so a timer can be set. Ho...
