About this Gig
I design precision sensor and data acquisition PCBs for engineers who need accurate measurements. This service covers sensor interfaces, analog front ends (AFE), signal conditioning, precision ADCs, filtering and amplification.
I can develop instrumentation amplifiers, voltage and current measurement, thermocouple and RTD interfaces, strain gauge and load cell inputs, Wheatstone bridges, low-level acquisition and analog-to-digital conversion. Designs can include filtering, gain stages, references, protection, calibration provisions and MCU interfaces such as STM32, ESP32, SPI and I2C
For precision measurement, layout is critical. I consider analog/digital partitioning, grounding, return paths, differential routing, noise coupling, EMI, thermal drift and sensitive nodes to preserve signal integrity
This gig is ideal for industrial instrumentation, laboratory equipment, test and measurement, environmental monitoring, automation, sensor modules and custom DAQ hardware. Depending on scope, I can provide schematic design, component selection, simulation, PCB layout, BOM and manufacturing files
Send your sensor type, signal range, accuracy target and sampling rate before ordering

FAQ
Can you design a precision sensor interface PCB?
Yes. I can design the sensor interface, analog front end, signal conditioning, ADC section and PCB layout around your sensor specifications and measurement requirements.
Can you design a precision ADC circuit?
Yes. I can select and integrate suitable ADCs based on resolution, sampling rate, input range, reference requirements, noise performance and the required measurement accuracy.
Do you design instrumentation amplifier circuits?
Yes. I can design instrumentation amplifier and low-noise analog front-end circuits for differential sensors, strain gauges, load cells and other low-level measurement applications.
Can you design thermocouple and RTD interfaces?
Yes. I can develop thermocouple and RTD measurement interfaces with appropriate amplification, filtering, reference circuitry and ADC integration.
Can you design strain gauge or load cell electronics?
Yes. I can design Wheatstone bridge interfaces, instrumentation amplification, excitation, filtering and precision ADC acquisition for strain gauge and load cell systems.
Can you make the PCB low noise?
Yes. I consider analog/digital separation, grounding, return paths, sensitive routing, filtering, power integrity and noise coupling during schematic and PCB development.
Can you design a multi-channel DAQ PCB?
Yes. I can develop multi-channel data acquisition hardware with multiple sensor inputs, analog front ends, precision ADCs, MCU connectivity and scalable channel architecture.
What files will I receive?
Depending on the package, deliverables can include schematic files, PCB layout, BOM, Gerbers, manufacturing outputs, source files and relevant design documentation.
Can you work with an existing schematic or PCB?
Yes. I can review, improve, troubleshoot or redesign existing sensor acquisition hardware, including signal conditioning, ADC, analog layout and noise-related problems.
What do you need before starting?
Send the sensor datasheet, signal range, expected accuracy, sampling rate, supply voltage, number of channels and preferred MCU or ADC if already selected. I can then recommend an appropriate architecture.
