If you need to quantify distance: SHARP 2Y0A02, IR sensor (λ = 850 ± 70nm) At-a-glance useful details: Sensing range: 20 - 150 cm Power requirements: 4.5 - 5.5 V (typ current consumption = 33mA) link to datasheet Output voltage is not linear with...

Thanks to the Engineering Excellence Fund, we acquired over 50 new sensors the summer of 2026 that are inventoried, tested, and ready for student checkout Fall 2026. Here's what's new for Fall 2026! Everything below is available for checkout from the ITLL El...

So you want to sense temperature. There are several things to consider as you decide between the various options. For most (room temperature +/- 50 degrees) applications, you could use any of the options below. So how do you decide?! Read on.  _______________...

Overview The seeed studio ESP32-S3 is a small Wi-Fi and Bluetooth enabled microcontroller that is about the size of a thumbprint!  To get started   seeed studio has good documentation to get you up and running: https://wiki.seeedstudio.com/xiao_esp32s3_...

Overview Vernier is a company that makes plug-and-play sensors for hands-on science education. We supply many Vernier sensors to BMEN classes for their labs, and students (outside of BMEN) are welcome to check out sensors directly from the Electronics Center...

This is a nice link: link Type T thermocouples (Cu/constantan or blue/red) have an accuracy of $/pm$ 1 degree C, whereas Type K thermocouples have an accuracy of $/pm$ 2.2C. 

Two options: Single PCB with LED and transceiver LED and transceiver from Treston (BYOC or build your own circuit) Good for: Detecting a moving object less than few inches away from the sensor

Author: Claire Porter Overview Hall sensors are available from the Treston. The presence of a magnetic field switches their output pin (pin 3) from HIGH to LOW.  Detection distance: ~1cm  Pictures illustrating short range of sensor To test the range of ...

The ITLL offers: The ITLL Electronics Center has over 300 sensors available for student checkout. In addition, some sensors are available for free (and do not need to be returned) in the Treston spinning console.  Typical check out period: 2 weeks How to ch...

Accelerometers measure motion, vibration, and mechanical shock. Inside of an accelerometer is an internal mass that is static until it experiences a change in velocity. This acceleration causes the mass to press to move, and it will press upon either a piezoel...

Several student projects desire using a BuffCard for authentication. Most commonly, I have seen these sorts of projects for secure bike locking.  Cheap RFID reader I set out to see if this is possible with a cheap Amazon RF ID-RC522 like these ones that av...

Available for checkout from the ITLL are three main types of humidity sensors, and this week I decided to test them against each other.  HIH-4030 (code available on my Github)  DHT-11 (code available on my Github) Indoor 2-in-1 Humidity/Temp monitor ...

In this guide, I will walk you through setting up a strain gauge measurement with a NI-9237 DAQ (both strain gauges and NI-9237 DAQ are available for checkout) in the quarter bridge (1 active strain gauge) configuration. Other configurations are possible.  ...
