For Customization:
    The formaldehyde transmitter designed by our company adopts electrochemical sensor with high measurement accuracy, fast response, long service life and long stability. The output resolution of the device can reach 0.01ppm, and it can be monitored online for 24 hours. Smart homes, air fresheners, air conditioners, etc. require long-term online monitoring of formaldehyde concentrations in industries or equipment. The device adopts wide voltage 10-30V DC power supply, 485 signal output, standard Modbus-RTU communication protocol, ModBus address can be set, baud rate can be changed, communication distance is up to 2000 meters. Note: The actual product may vary in slight variation with the image shown. Refer to the datasheet in the ATTACHMENTS section for more info. regd. the product.

Features:

  1. Range 0-5ppm, other ranges can also be customized.
  2. High measurement accuracy and repeatability up to ±2%.
  3. 485 communication interface standard ModBus-RTU communication protocol, address, baudrate can be set, the communication distance is up to 2000 meters.
  4. Optional high-quality OLED display, the value can be directly viewed on the spot, and the nightcan be clearly displayed.
  5. On-site power supply adopts 10~30V DC wide voltage power supply, which can adapt tovarious DC power supplies in the field.
  6. The product adopts wall-mounted waterproof case, which is easy to install and has highprotection level and can be applied to harsh environment.

Applications:

A temperature and humidity module can be added inside the shell to realize the joint detection of temperature, humidity, and formaldehyde.

Package Includes:

1 x Renke RS-CH2O-N01-2-5P-2 Formaldehyde Sensor 40°C~+80°C,≤±0.5ppm (Type RS485)

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.
