1, Introduction
TP-1,TP-1.1 normal temperature gas sensor is TP-2's brother. it is also made of SnO2 multi-crystalloid appending propriety extender. it has tiny pearl structure. It can detect hydrogen, charocoal, natural gas, LPG, etc. The advantages are normal temperature, simple circuit, lower power consumption, low price, longer life.
2, Operating Condition
1) Operating voltage: 6V~12V
2) Operating circuit: see Fig 1
3) The selection of RL
Operating circuit The selection of RL
Model Voltage RL(Ω)
TP-1 9V-12V 100

4) Static power consumption:≤0.2W
5) Environment: temperature-30°C~+50°C relative humidity≤95%
6) Time of stable values:≤3minutes
3、Sensitivity Response
4, Features
1) The voltage on the RL in the air:V1≤2.5V
2) The voltage on RL in the 4000oom LPG: V2≥5V
3) Sensitivity:V1/V2≥2
4) Response time:<10s
5) Resume time:<20s
