Cheap voc sensor for air purifiers and ventilation system tgs2600
Model number: tgs2600
1.Features:
* low power consumption
* high sensitivity to gaseous air contaminants
* long life and low cost
* uses simple electrical circuit
* small size
2.Description
The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater.
In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air.
A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The tgs 2600 has high sensitivity to low concentrations of gaseous air contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke.
The sensor can detect hydrogen at a level of several ppm.
Due to miniaturization of the sensing chip, tgs 2600 requires a heater current of only 42ma and the device is housed in a standard to-5 package.

Water fluid liquid level sensor llc200d3sh
Model number: llc200d3sh
1.General description
The liquid level sensor provides a single point detection via a
Ttl compatible output.
An infra-red led and phototransistor accurately positioned at
The base of the cone ensure good optical coupling between
The two when the sensor is in air. When the sensor’s cone is
Immersed in liquid, the infra-red light escapes from the cone
Causing a change in the amount of light at the phototransistor
Which makes the output change state.
2. Cleaning
Proper fluids should be selected based on type of
Contamination to be removed. Sst sensing recommends
Freon and alcohol based solvents. Do not use chlorinated
Solvents such as tricholorethane as these are likely to attack
The sensor material.
3.Liquid media compatibility
Before use check that the fluid in which you wish to use these
Devices is compatible with polysulphone.

Parameters
Brand: TOPTITECH
Size: Dia14*27H
Pore size:30microns
Application: temperature and humidity sensor protection cover
Features
High Porosity: Porous Ti elements exhibit a high degree of porosity, which allows for excellent permeability to air and moisture. The interconnected network of small pores enables the ingress and egress of gases while providing a physical barrier against larger particles. This feature ensures efficient ventilation and prevents the accumulation of moisture or contaminants on the sensor surface.
Thermal Stability: Titanium is renowned for its exceptional thermal stability. Porous Ti elements can withstand a wide range of temperatures without experiencing significant structural changes or degradation. This property is especially crucial for temperature sensors, as it ensures the protection cover can endure extreme conditions without affecting the sensor's performance.
Corrosion Resistance: Titanium exhibits excellent corrosion resistance, making it an ideal material for sensor protection in humid or corrosive environments. Porous Ti elements are highly resistant to various chemicals, including acids, alkalis, and salts. This corrosion resistance extends the lifespan of the protection cover and maintains the sensor's accuracy and reliability over time.
Lightweight and Durable: Porous Ti elements are lightweight yet durable, providing a balance between mechanical strength and weight reduction. Their low density makes them suitable for applications where weight is a concern, such as aerospace or portable sensor devices. Additionally, the robust nature of porous Ti ensures longevity, reducing the need for frequent maintenance or replacement.
Applications
