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 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 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.

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.

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

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.
