Power subsystem
Battery power supports the sensor, converter and controller. Voltage, noise, protection and runtime are integration-test items.
TECHNOLOGY
From small signals
to traceable records.
We separate the stages between the sensed signal and the record a customer reviews, validating hardware, device software and data layers step by step.
EOS system architecture
This is the functional architecture under development. Components and interfaces are finalized through physical integration tests.
- 01
Sensor input
Electric-field changes near the target
- 02
Analog front end
ADA4530-based signal conditioning
- 03
Analog-to-digital conversion
Convert the conditioned signal to digital samples
- 04
Device control
ESP32-S3 · time, health and data packets
- 05
Collect, store and review
HTTP API · device history · interface
Recording and transfer
Readings are associated with device ID and time. Transfer under site communication policies and offline storage require further review.
The sensor is only part of the answer.
Distance and target
Field conditions vary with target size, potential and geometry. One metre is a validation target, not a guaranteed capability.
Surroundings
Metal structures, grounding, orientation and motion must be included in reference comparisons.
Record quality
Record device health, missing samples and conditions to establish the limits of analysis.
