Overview
Description
The DAQ on a Stick with Honeywell Pressure Sensor uses Renesas' data acquisition (DAQ) on a stick reference design with Honeywell's NBP Series-Uncompensated/Unamplified 0psi to 30psi basic board mount pressure sensor. This demo shows a complete signal chain solution from the Honeywell sensor, signal conditioning using Renesas' precision parts and a Renesas microcontroller. The complete reference design is conveniently housed in a USB stick form factor with a plug-in sensor board. This compact design draws power through the USB port and uses a graphical user interface (GUI) to display the real-time voltage readings from the pressure sensor. The board image on this page shows the DAQ on a stick connected to an external pressure sensor. Pressure is applied to the Honeywell sensor via a syringe.
The image below shows a simplified schematic of the pressure sensor design. The design uses the Honeywell NBPLLNN030PGUNV 0psi to 30psi basic board mount pressure sensor, the Renesas ISL28134 chopper amplifier, ISL22316 digitally controlled potentiometer (DCP), ISL43840 dual 4-channel multiplexer (Mux) configured as a differential Mux, ISL21010 4.096V voltage reference, ISL21010 3.3V voltage reference, ISL26102 24-bit Delta-Sigma converter, and R5F10JBC (RL78/G1C) microcontroller.
The installation application includes the following items:
- GUI software
- Desktop shortcut for easy access
- Application note and schematics
