Manufacturer Description Page

A large part of this class revolves around taking previously obtained information of former students and adding to it. The 2007 class started this list of manufacturers they contacted, some with success, and some without. Our aim this year is to flesh out what these companies offer, activate links to their information, and provide more information we can use in the future to find the sensors we need on a given project.

Assignment: Your assignment is to make personal contact (phone or email) with at least 1 sensor/electronics/materials manufacturer, requesting materials or demonstration unit(s) regarding a particular sensor you think might be interesting. Here's an example letter you can use as a starting point. Please edit as appropriate, and describe any potential uses you might have for the technology in question. Be polite, courteous and thank everyone for their time. Be sure to copy me on the note.

There are a multitude of sensor technologies that, without a polite contact, we’d never get to use. Sourcing of a part or technology from the manufacturer or distributor is a huge part of sensor specification and selection. This often includes requesting or negotiating documentation, free samples, demonstration units (often needing to be returned to the manufacturer) or product demos by company sponsors and salesmen.

Benevolence to students can benefit sensor electronics companies in a good number of ways. The most important of these is that students move into industry and will have a tendency to use more of a given company's products if they recall a positive interaction during their studies (there are studies within various engineering fields that have categorically proven this relationship). Also, students often publish/publicize their research that results from use of sensor technologies, dropping names along the way, providing residual publicity for the manufacturers. Finally, there are often waste testing materials, that otherwise need to be disposed of, that representatives and engineers are happy to donate.

You'll be surprised at how often you'll get a positive response, as any intelligent applications engineer is going to be personally interested in what you’re up to, and how they might help. In return, it's incumbent upon you not to abuse the favor by requesting too many samples, forgetting to thank your source, or failing to report any results.

Once you’ve contact a given manufacturer, please indicate that you’ve done so on the Wiki to avoid repeat inquiries being sent. Do not repeatedly inquire to the same email address, if you don’t get a response, they’re likely not interested in your inquiry. As long as you add notes on your experience with a company, you’ve completed the assignment.

If there are good noted here already, move on to another manufactuerer. Don't repeatedly inquire to the same email address, even if you don't get a reply. If you don't get a response, they're likely not interested. Simply post "No response" and the date here. Do not post anyone's full email addresses here; use links to their contact page instead. If you're given permission to use a representative's name, then list it, but ask first. Feel free to include any notes you have from your communications with the company below.

Manufacturer List


ultrosonic, air sensor, bang sensor, various of bend sensors, biobeat, biowave, bioflex, curl sensor,(expensive for those bio sensors),flash, tilt, hot (temperature) & humidity sensor, magnetic, loud (sound) sensor, orientation sensor, push sensor, approximity sensors, spin, touch, vibe sensor. a lot but expensive. some we could actually make by ourselves with cheap sensors.There is also a product called the I-CubeX Wi-microDig that enables us to interface sensors wirelessly to the computer. meng li


InvenSense exclusively manufactures gyroscopes, accelerometers, and packaged gyro/accelerometer/magnetometer devices. They cater to large tablet, smartphone, gaming, and television manufacturers, but smaller orders are possible through their website, which offers a free development corner (software downloads, discussion forum, and other info). InvenSense manufactures analog single axis gyroscopes, digital dual and triple-axis gyroscopes, digital six-axis motion processors (3-axis accelerometer and 3-axis gyroscope with their "Digital Motion Processor", which is able to process 9-axis algorithms "on board" by accessing an external magnetometer), and are releasing a fully integrated 9-axis gyro/accelerometer/magnetometer combo (the MPU-9150) in April 2012 (I submitted a request for a demo along with my inquiry on 2/7/2012). There are USB development versions of many of their sensors, including their popular MPU 6050 (a 6-axis gyro/accelerometer combo) which incorporates a 3-axis magnetometer, available for purchase on their website. This particular device uses I2C for digital output and they offer an ARM interface board to convert I2C to USB (though, there are several Arduino projects documented online). Software supports only Android, Linux, and Windows. jennifer shannon

Milone Technologies

Milone manufactures the eTape Liquid Level Sensor. The sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. Was used by ITP project Digi Drench. The sensor is available at Adafuit but also sold on Milone's website. We were able to obtain free samples from them; contact me if you want to try them out. lia martinez?

Gemssensors have many types of level sensors and temperature sensors. Eun Jung Park


They make many types of position sensors such as rotary position sensors, LVDT position sensors etc. Eun Jung Park


Parallax sells accelerometers, touch sensors, temperature, humidity and pressure sensors. And for me the most interesting sensors are light sensor and color sensor. Also this company provides good sources and descriptions for each sensor like codes of datasheets. Eun Jung Park


Celesco makes some great string-potentiometers, in various sizes all the way up to robust industrial. They also have industrial linear potentiometers useful for larger sensing needs. jamie

Emfit jamie modified by ~aad316?

Manufactures ferroelectric sensors and embedded electronics for bio-sensing. Some examples are fall, wandering, and epileptic seizure alarms. One specific sensor is a large bed sensor which they claim can detect slight movement, respiration and even heart rate. jamie

Sewori jamie modified by ~aad316?

Manufactures a few types of sensors such as GPS, LCD, ultrasonic, parking, DMB and image sensors. China's largest ultrasonic sensor manufacturer and claims to manufacture an ultrasonic sensor that can detect over twice of its competitors. Ultrasonic sensors can be purchased as part of a parking sensor unit or alone.

Vernier aad316

Vernier manufactures over 50 different sensors for educational application. The sensors can be purchased alone for OEM use or with a portable data logging device to record and view the sensor's data. Curriculum based applications for sensors are available. Some examples of the sensors available include: CO2 sensor, blood pressure, sound level, EKG, dynameter, etc.Good place to visit if you are looking for a specific sensor as they seem to have nearly all applications available. jamie
