The Renke RS-CH2O-N01-2-5P-2 is a high-precision electrochemical formaldehyde sensor designed for reliable 24-hour indoor and industrial monitoring. With a measuring range of 0–5ppm and a resolution of 0.01ppm, it ensures fast, accurate detection of formaldehyde for healthier environments. Its durable wall-mounted waterproof design allows use in harsh conditions, and optional OLED display provides real-time readings. Equipped with RS485 output, it supports centralized monitoring through a cloud platform. The sensor offers excellent repeatability within 2%, low drift, and long-term stability, making it ideal for homes, offices, labs, and factories seeking continuous air quality management.


Features:

  1. High-accuracy electrochemical formaldehyde detection (0–5ppm)
  2. Fast response time ≤35s for real-time monitoring
  3. Long-term stability with ≤7% signal drift per year
  4. Optional high-quality OLED display for clear on-site readings
  5. Wall-mounted waterproof design suitable for harsh environments
  6. Supports RS485, 4–20mA, 0–5V, and 0–10V outputs for flexible integration

Application:
  1. Indoor air quality monitoring in homes and offices
  2. Industrial and laboratory formaldehyde detection
  3. Centralized multi-location environmental monitoring via cloud
  4. HVAC system air quality control
  5. Schools, hospitals, and public buildings safety monitoring
  6. Furniture and building material off-gassing detection

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
