There are ADC with internal PGA that can measure thermo couples. ADS1118 has e.g. about 0.2 K resolution and a few K absolute accuracy, also an internal temperature sensor suitable as cold junction reference. That's not mind blowing but suitable for many applications.
Hello experts, Currently i am Working on Autoclave. So i Need to select a pressure sensor for reading the pressure maximum range should be 4 bar. But i am bit confused about pressure types. I have to measure the pressure which is going to generate inside of the chamber. What kind of pressure sensor i need to use? whether
It's wrong to say that the transducer "requires 150Vpp" drive signal. The specification is a maximum rating "allowable input voltage". Most applications use a lower drive level. As betwixt mentioned, we have to look at the application requirements to understand what's an appropriate drive level. Similarly a reasonable matching circuit depends st
There are circuits designed for multipurpose applications, so you will find in some cases a whole region of the board without components, as for example if for a specific project do not need some kind of communication, some sensor, etc...
Hi I will design 3D laser displacement profiler but don't have CMOS Image sensor information. What is a CMOS Image sensor company or product information for 3D Laser displacement profiler? Thanks
I think there are many applications. It can be perimeter security sensor placed in the corner of building or area to form two beams using single transmitter. Or it can be simple old-designed roadside FMCW traffic counter, upgraded with two-beam antenna, so it can estimate vehicle speed with higher accuracy using time difference between beams. Data

If your processor runs directly off of 3V, and you've got a 3V battery, you certainly don't need a regulator. Many of the PICs will run down to 1.8V, which is probably the point where the battery is dead. Unless you need to maintain a specific supply voltage (for your sensor, for example) the regulator would only make things less efficient.
Hall sensors are used in professional voltage transducers, e.g. in traction applications (electric locomotives). The transducers are comprised of a series resistor and a hall sensor with a large number of primary turns. This way you get an isolated AC/DC voltage transducer that doesn't need a primary supply. The sensors are (...)
There isn't a thing like "the best gas sensor". There are different applications, e.g. explosion protection, monitoring of toxic or hazardous substances, different selectivity and performance requirements, possible power, size and cost constraints. What are your application and additional requirements?
Reading Nemoto web information carefully, you'll be aware of this general statement about catalytic sensor usage ?Not like semiconductor type sensors, a long preparatory aging time is not necessary for performance stabilization. ?In case of gas detector applications, aging for 10 minutes would be enough before calibration. Calibration can

Hi, For any biomedical applications, the sensor output has to be amplified and digitized. For amplification, we use Instrumentation amplifier. But the output of IA has some dc voltage. So, how to suppress the dc voltage. At the same time, all biomedical signals are low frequency signals in the order of 0 to 20Hz. Which filter technique is bette

Hi, I am designing a circuit where I need to know whether the device under test( in my case - it is a very small ic 2x3 mm) is placed on the tester. How do I detect the presence of the IC? Is there any sensor particularly for that kind of applications? Regards, S
I would like to ask about when is need to put a voltage follower (buffer) to a circuit. For example i create a circuit which has a transmitter/ receiver ...and use ultrasonic sensor. At the transmitter circuit i will need a voltage follower(buffer) before the sensor?
Normally hall effect sensors are quite enough, anyhow. You may use proximity sensors (Inductive for metalic sense and Capacitive for Other senses) These proximities are coming in wide ranges, and are high speed. but these sensors are expansive than hall effect sensors. Other idea is to use encoder or simple DC motor (...)
Hello Everyone, I am trying to make a Wireless Robot by using 3-Axis Accelerometer sensor. But I am new to this sensor... So can any one give me some brief explanation of this sensor... How many types are there of such sensor? Which sensor should I use for my project? Is it a programmable (...)
The piezo buzzer will need a little mod. Adding mas can change the resonant frequency and increase sensitivity of the sensor to suit specific applications. Try to glue one edge to your project and fix a bolt to the other edge. The rest of the disk (and the bolt) are not touching anything and are free to move/flex. A simple circuit to inte

hi,all, now i am designing a high precision low offset fully differential PGA with cmos process for sensor applications, pls give me some circuits and papers, books, related resources or some suggestions. many thanks!
As in most similar threads, I miss a resolution (for digital sensors) and accuracy specification. For a high initial accuracy without calibration of the sensor, most people would prefer a Pt100 or Pt1000 sensor. It's the unchallenged standard for industrial applications up to 400° C.
Hi, I've started an open-ended design project and I'm looking for ideas for a design of a micro pressure sensor, can anyone recommend any new/interesting applications that I can work from for my design? Doesn't have to be an original idea; just something interesting I can adapt. Thanks, Ely

I have looked extensively online but can't seem to find a source for RGB color sensors. Any suggestions?
There are no polarized and non-polarized transducers. All have (or should have) a polarity marking relating input voltage to sound pressure polarity. It's meaningless in most applications. The sensor's datasheet is somewhat incomplete. Do you expect to get the missing information from edaboard users? But fortunately, these 40 kHz (...)
Hi, You could use a PT100 sensor. Take a look this helps. Tahmid.
Generally, this sensors have data sheets and specifications. They tell about the circuit and the electrical data. At zero pressure (assuming you have a relative pressure sensor), the differential output voltage can be slightly negative due to offsets (-> specification). For simple measurement applications, a single OP differential (...)
