I will precision adc firmware for sensor calibration and high resolution measurement
Embedded Firmware Engineer for Sensor Data Acquisition and Precision
I develop embedded firmware for reliable sensor measurement data acquisition and industrial monitoring using STM32 ESP32 and Arduino. My work covers multi sensor integration timestamped data logging R...
About this Gig
Most measurement projects fail because the firmware only reads raw ADC codes. Real precision needs proper configuration, calibration, noise control and conversion into trustworthy engineering units.
I build production grade precision ADC firmware for external high resolution converters and MCU internal ADCs. Focus areas include ADS1115, ADS1220, ADS124S08, AD7124, MCP3561 families as well as optimized STM32 and ESP32 sampling chains.
What you actually get:
Correct sampling rate, PGA and reference setup for your sensor range
Multi point or system calibration removing offset and gain errors
Temperature compensation using measured drift coefficients
Oversampling + decimation and outlier rejection for lower noise
Ratiometric measurement support for RTDs, load cells and bridges
Linearization curves or polynomial scaling into volts, amps, °C, pressure etc.
Clean documented C code ready for integration
Buyers who need reliable voltage measurement, current sensing, instrumentation firmware or laboratory grade data acquisition stop guessing and start shipping accurate products.
FAQ
Do you work with external precision ADCs like ADS1115 ADS1220 AD7124?
Yes. I write complete drivers and calibration routines for popular high resolution external ADCs as well as optimized internal STM32 and ESP32 ADC channels.
What calibration methods do you implement?
Offset and gain correction, multi point system calibration, temperature compensation, and linearization curves so raw counts become accurate engineering units.
Can you reduce noise and improve effective resolution?
Yes. I apply oversampling, decimation, averaging with outlier rejection and digital filtering to raise effective number of bits and stabilize readings. Do you support RTD thermocouple and bridge sensors?
Do you support RTD thermocouple and bridge sensors?
Yes. Ratiometric measurement, cold junction compensation and proper excitation handling are included when required for accurate sensor
Will I receive documented source code and accuracy notes?
You receive clean commented firmware plus a short accuracy summary showing what error levels were achieved after calibration.
