The circuit shown in Figure 1 is a 12-bit, 1 MSPS data acquisition system utilizing only two active devices. The system processes charge input signals from piezoelectric sensors using a single 3.3 V supply and has a total error of less than 0.25% FSR after calibration over a ±10°C temperature range, making it ideal for a wide variety of laboratory and industrial measurements.

The Sound Impact Sensor provides a means to add noise control to your project and responds to loud noises such as a clap of the hands.

The MAXREFDES27# is a tiny IO-Link proximity sensor with an IR receiver, matching IR LED driver, IO-Link transceiver, and energy-efficient step-down converter all on an 8.2mm x 31.5mm printed circuit (PC) board. Maxim Integrated and Technologie Management Gruppe Technologie und Engineering (TMG TE) collaborated in designing the MAXREFDES27# as an IO-Link version 1.1/1.0 compliant proximity sensor…

This reference design features an ultrasonic distance sensor that fits in a M12 housing due to its high integration and an optimized layout. The design offers an IO-Link interface to communicate with the system control, which makes it industry 4.0 ready.

TIDA-01519 reference design offers a smart enivromental sensor and home automation solution for sensor to cloud applications

The LDC0851EVM (Evaluation Module) demonstrates the use of inductive sensing technology to accurately detect the presence of a conductive target object passing a fixed threshold. The module includes a perforated and interchangeable 4-layer PCB where both the sensing coil as well as the reference coil are stacked for reduced system size.

This design provides a complete solution for pH sensor with temperature compensation. The circuit has three critical stages: the pH probe buffer, the ADC, and the digital and power isolator.

The MAXREFDES117# reference design is a low power, optical heart-rate module complete with integrated red and IR LEDs, and a power supply.

Alarm will sound at 6.0V for 2 cells and 9.0V for the 3 cell configuration. Current draw: 5.5mA @ 7.4V (alarm off) : 29mA at 6.0V (alarm on). Simple ‘dead bug’ construction weight was 2.9 grams.

The MCP3421 Weight Scale Demo Board works with the LabVIEW™ Graphical User Interface (GUI) PC Software. This demo board demonstrates how to use the MCP342118-bit Delta-Sigma ADC for weight scale applications.
