ESP8266 WiFi – CO2 sensor T6613 (ArduinoIDE)

Hardware

Informatie (ENG)

The T6613 is a CO2 Module designed to meet the volume and delivery expectations of Original Equipment Manufacturers (OEMs). The module is ideal for customers who are familiar with the design, integration and handling of electronic components. All units are factory calibrated to measure CO2 concentration levels up to 2000ppm.

Flexible CO2 sensor platform designed to interact with other microprocessor devices
Eliminates the need for calibration with Telaire’s patented ABC Logic™ software
Lifetime calibration warranty
0 to 2000ppm Measurement range
400 to 1250ppm ± 30ppm or 3% of Reading accuracy
UART at 19200baud digital output
0 to 4VDC Analogue output
0.9W Peak power consumption
Interface connections designed for 12-pin male header with 0.1in (2.54mm) spacing
