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 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...

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...

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...
