Sensors - Detectors Projects
Digital Pressure Gauge 0 to 10kPa (0 to 1.75 psi) with OLED display
The project presented here is a Digital Pressure Gauge using an OLED display.
Analog Light Sensor + Light Sensitive Switch using OPT101
You may have seen many light-sensitive switch circuits based on an LDR sensor.
Liquid or Air Pressure Switch with Relay
This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay.
Strain Gauge Sensor Amplifier or Single Supply Instrumentation Amplifier
This is a new project, a single supply instrumentation amplifier with onboard bridge configuration, and a 2.5V precision reference voltage chip.
Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield
The project presented here is a photodiode amplifier for visible light.
Reflectance based Proximity Sensor using Si1102
This reflective sensor module is a high-performance 0-5 cm active proximity detector.
0 to 5V output Analog Hall Sensor for Foot Controller
This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range.
Proximity Distance Sensor using DRV5053 Hall effect Sensor
This is a hall sensor proximity sensor that can detect magnetic targets approaching the sensor, without physical contact with the target.
New and Improved Geiger Counter – Now With WiFi!
In one of our previous tutorials, we examined the development of a DIY-Geiger Counter showing the efforts of “Instructable” user Prabhat who combined the ESP8266 with a touch screen display to create a truly intuitive version of his Geiger Counter.
Capacitive Touch Sensor Toggle Switch
Touch sensors are used in many applications, from remote controls, LED light controls to appliance control panels.
Current Limit Solid State Power Switch with Latch
The project published here is a solid-state power switch with current limiting that prevents damage to host devices from faulty load conditions.
Window Comparator – Window Detector with relay output
A window detector circuit, also called window comparator circuit or dual edge limit detector circuit is used to determine whether an unknown input is between two precise reference threshold voltages.
