Air, Noise, and Water Quality Monitors
Environmental monitoring stations are deployed in exposed locations and serviced infrequently. Solar power budgets need to be validated in production, not discovered in the field. Sensor cartridge serialization, cellular provisioning, and enclosure sealing are all production-line decisions that determine data quality over the deployment lifetime.
Buyer pains we hear most
- Sensor cross-sensitivity drift between gas species degrades data quality and is rarely caught before field deployment
- Solar power budget shortfalls appear only under real-world insolation and load conditions, not bench testing
- Sensor cartridge serialization must follow the cartridge through field swaps, not stay with the station
- Outdoor mounting hardware is frequently under-specified in the BOM and causes field failures
Typical product traits
- Electrochemical cell or NDIR optical gas sensor front end
- Solar charge controller with LiFePO4 buffer battery management
- LTE-M or NB-IoT cellular modem with antenna and SIM provisioning
- Replaceable sensor cartridges with per-cartridge calibration data storage
Regulatory environment
PM ambient air quality
EN 12341
Air quality sensor performance
CEN/TS 17660-1
IP rating test
IEC 60529
EMC for measurement equipment
IEC 61326-1
Test plan considerations
- Per-unit sensor channel calibration with reference gas at defined concentration
- Solar charger input and battery management functional test per unit
- Cellular registration and data transmission test before enclosure sealing
- IP enclosure integrity test on assembled samples per batch
Frequently asked questions
Do we need a written test plan?
Yes. A production test plan defines pass and fail criteria, FCT vectors, calibration steps, and serialization rules. We help draft one if your team has not written one yet, based on your firmware behavior and target field performance.
How do you serialize and label units?
Per-unit MAC, UID, and serial number assignment with GS1 DataMatrix or QR labels. Polyimide or polyester label stock based on environmental requirements. Every label is logged against board lot, firmware hash, and test result for full traceability.
Do you support RoHS and REACH compliance?
Yes. We work with RoHS-compliant component selection and SAC305 lead-free solder by default. REACH substance documentation comes from supplier declarations forwarded with each batch.
