A sensor reading you can trust, from the probe to the firmware.
We design the front end, choose the converter, write the driver and calibrate the result, so the number your product reports is a measurement and not a guess.

Your product has to measure something, and the readings are noisy, drift or disagree with a reference.
Maybe a sensor board worked on the bench and does not behave on your own board, a thermocouple reads several degrees off, or a load cell wanders when a motor starts. Trouble like this often sits in the signal path around the sensor, so we look at the whole path: sensor, front end, converter, reference, grounding and firmware.
A measurement you can build a product on.
- The sensor, matched to the job Integration of thermistors (NTC/PTC), thermocouples with cold-junction compensation, RTDs (PT100/PT1000), load cells and strain gauges, IMUs and accelerometers, current sensing (shunt and Hall), humidity, pressure and gas sensors, and encoders, chosen for the range, accuracy and environment you describe.
- Front end and converter Excitation, amplification, filtering and protection sized to the sensor signal, and an internal or external ADC chosen for the resolution, noise and speed the measurement needs.
- Calibration A calibration method for the sensor and the board, such as offset and gain, or a linearization curve like Steinhart–Hart for a thermistor, with notes on how the constants are stored and updated.
- Noise and grounding The analog path laid out and grounded in the PCB, with filtering and averaging in firmware, so the reading holds up while the rest of the product is running.
- Firmware drivers Drivers for the sensor over its analog, I²C or SPI interface, written against the datasheet and errata in C, bare-metal or RTOS.
- Production test of the sensor path A test step that checks the sensor path on each unit with our automated test fixtures, so a bad sensor or a bad solder joint is caught before the unit ships.
Four steps from a measurement need to a verified reading.
- 01 Tell us what to measure Send the quantity, the range and accuracy you need, the conditions the sensor lives in, and the sensor, board or firmware you already have, through the quote form.
- 02 Choose the signal path We pick the sensor, front end and converter with you, using parts you can actually buy, and write down why.
- 03 Build and measure on real hardware We build the circuit on a real board, compare the readings with a known reference, and calibrate.
- 04 Hand over You receive the schematic, the driver and calibration notes, and the production test step, as listed in your quote.
Before you ask
Which sensors do you integrate?
Thermistors (NTC/PTC), thermocouples with cold-junction compensation, RTDs (PT100/PT1000), load cells and strain gauges, IMUs and accelerometers, current sensing (shunt and Hall), humidity, pressure and gas sensors, and encoders. If yours is not on the list, send it with the quote request and we will say plainly whether we can take it on.
Our sensor reading is noisy or drifts. Can you fix it?
We start from the signal path: the front end, the reference, the grounding and the firmware filtering, and measure each against a known reference to find where the error comes from.
Do you calibrate and test the sensor on every unit?
We design the calibration method and the production test step. Whether each unit is calibrated individually depends on the accuracy the product needs, and we settle that with you in the quote.
What should I send to get a sensor quote?
What you need to measure, the range and accuracy, where the sensor sits and what it is exposed to, and the sensor, board or firmware if you have them. Send it through the quote form.
