Chemical Sensors Philippines: Gas, Air Quality, pH/EC & Water Quality | Circuitrocks

Chemical Sensors at Circuitrocks — Gas, Air & Water Quality Monitoring

Build reliable environmental monitors with chemical sensors for gases (CO, LPG, smoke, alcohol), air quality (VOC/CO₂/PM), and water chemistry (pH, EC/TDS, ORP, DO, salinity). Compatible with Arduino, ESP32, and Raspberry Pi.

Gas (MQ series) • VOC/CO₂/PM • pH/EC/ORP/DO • TDS & Ammonia • I²C/UART/Analog

Why choose these sensors

  • Wide coverage from hobby gas detectors to lab-grade water probes
  • Easy integration via I²C/UART/analog with rich libraries
  • Scalable for classrooms, farms, aquaculture, and industry pilots

What you can build

  • Indoor air-quality dashboards (CO₂/VOC/PM)
  • Hydroponics & aquarium controllers (pH, EC, DO)
  • Gas leak/smoke/alcohol alerts (MQ series)

Recommended add-ons

Featured categories

Gas & Air Sensors

Tip: Calibrate regularly. Water probes often require temperature compensation; use an RTD/thermistor input when available.

FAQ

Are these compatible with Arduino/ESP32/Raspberry Pi?

Yes. Most modules expose I²C, UART, or analog outputs with available libraries/examples.

Do gas sensors need burn-in or calibration?

Yes—MQ sensors typically need minutes to hours of burn-in and periodic calibration. Follow each product’s datasheet.

How do I maintain pH/EC/DO probes?

Use proper storage solutions, rinse (don’t wipe) pH glass, and re-calibrate with fresh standards. Add temperature compensation where supported.

Do you ship nationwide?

Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
