YJJ TB200B-ES1-O2 UART I2C Oxygen Sensor Module 0-25% for enclosed space detection

Features:

Project Details
Power supply voltage DC 3.3V~5.5V wide voltage supply, suitable for microcontrollers, PLCs, and IoT motherboards
Operating current Normal full load < 5mA; UART normally open about 2.5mA - 5V; sleep mode as low as 0.8mA @ 5V
Conventional power consumption Full load 25mW (5V); sleep power consumption within 25mW, suitable for low-power devices
Hardware interface Standard TTL 3.3V UART; optional I2C; 4-pin leads (VCC/GND/Signal/Reserved); active upload + question-and-answer dual mode switchable
Communication protocol Standard serial port instructions, built-in calibration, reading concentration, reading temperature and humidity instructions; data comes with checksum error prevention
Preheating stabilization Clean air power-on stabilization ≤ 120s; polluted environment ≤ 180s; no need for external complex conditioning circuit
Certification RoHS compliant, exportable to Europe, America, and Southeast Asia complete equipment
Guarantee 12-month factory guarantee; sensor body normal service life ≥ 5 years, resistant to poisoning, and able to withstand harsh working conditions
II. Environmental Adaptation Parameters 
Operating temperature: -40℃ ~ +55℃; optimal range 20~35℃, excellent high and low temperature drift control
Operating humidity: 15%~95% RH (no condensation); recommended 50% RH; no condensation or water ingress to damage sensing electrode
Air pressure tolerance: standard atmospheric pressure ±10%, mine, plateau, and sea air pressure fluctuations do not cause false alarms
Anti-interference: built-in algorithm anti-oil smoke, water vapor, and common organic gas cross-interference, small baseline drift; annual long-term drift < 5% FS
III. Built-in Temperature and Humidity Integrated Module Parameters (Module Comes with)
Temperature detection: range - 40℃~85℃, typical accuracy ±0.2℃, real-time temperature compensation for gas concentration
Humidity detection: range 10~95% RH (no condensation), typical accuracy ±2% RH
Advantages: automatic temperature and humidity correction, stable detection accuracy in high and low temperature humid environments, no need for external temperature sensing compensation
IV. Mechanical dimensions and weight
Bare PCB circuit board: 40×30×5.6 mm
Complete TB200B-ES4 (including ES4 sensor probe): 40×30×22.45 mm
Overall machine weight: < 25g, small in size, easy to be embedded in distribution boxes or portable detection instruments
Reserved fixing screw holes, convenient for snap-in / screw fixation; standard 4-pin matching cables available for purchase
V. Commonly detectable gases, main flow range, response capability
ES4 can be customized for over twenty types of toxic and harmful gases. Main standard model performance is unified:
Response speed: T90 ≤ 30s; T50 ≤ 10s; zero point nitrogen return zero time ≤ 120s
Accuracy: full-scale error ±5% FS; repeatability < 1%; good linearity
Resolution uniformly standard 0.1ppm (trace gases can be customized 0.001ppm)
