2. Product Overview
HPD05 PM2.5 Sensor Module use principle of optical scattering to measure concentration of dust inthe air,the module built in a Infrared Transmitter and a high sensitive Photoelectric Receiving Sensor the Infrared Transmitter emits light and the light meets the dust to produce the scotch light, theintensity of the scotch light detected by Photoelectric Receiving Sensor reflects the concentration ofdust in the air, HPD05 have two ways to output current concentration data, one is PWM signal (thewidth of signal is the value, 1ms = 1ug/m3), the other is IIC signal(unit is ug/m3).
HPD05 can be used for Air Cleaner, Air Conditioner with purifying function, Fresh Air System and air quality testing equipment.
3. Detecting Principle
Detecting Principle
Per the principle of optical scattering,the Transmitter emits light, and the light meets the dust to produce the scotch light, the high sensitive Photoelectric Receiving Sensor detects the intensity of the scotch light then output intensity signal, current which is proportional to the size and quality of intensity of the scotch light, the current is amplified by amplifier and calibrated by CPU, finally output digital PWM signal or IIC data of concentration of dust.

"The TandD RTR-574-S Wireless Temperature Humidity Light Data Logger
The RTR-574-S Wireless Temperature Humidity Light Data Logger includes two sensors that simultaneously measure and record illuminance / UV intensity and temperature/humidity. This high accuracy data logger allows for the measuring and recording of the above items in various places such as facilities where people gather, where important documents and fine arts are being stored or displayed, where food and drink are being stored. Also, cumulative illuminance and the cumulative amount of UV light can be easily viewed even without stopping recording."
The DTBH zero-temperature thermostat is a device that can provide a stable and accurate zero-degrees Celsius temperature field for the thermocouple reference end for a long time. It is an ideal substitute for the traditional ice bucket and is very suitable for the verification / calibration of thermocouples. The technical specifications of the equipment are in full compliance with the new regulations "JJF1637-2017 Low-cost Metal Thermocouple Calibration Specification".

Supplier of walk-in environmental test chamber. Designed to perform high-temperature operations for large-sized test specimens. The multipurpose walk-in chamber is the perfect site for testing the components against humidity, temperature, and various climate conditions.
A temperature sensor is a sensor that senses temperature and converts it into output signal. The temperature sensor can accurately measures the ambient temperature and is widely used in agriculture, industry, workshops, warehouses and other places. This product measures the change in ambient temperature and outputs the temperature change value in the form of RS485 digital signal through inter processing. This product provides a temperature query command and provides digital signals at the same time. This product adopts RS485 half-duplex communication interface and is compatible with terminals with RS485 communication interface on the market, which is convenient for collecting temperature signals. The product has the characteristics of simple structure and convenient installation.
Scope of application
A variety of industries that require temperature, such as the food transportation industry, the pharmaceutical transportation industry, and temperature sensitive article storage industry.

High relative humidity can cause significant, possibly irreparable damage to sensitive equipment, supplies, and products. To ensure dehydration measures work, humidity indicator cards measure the relative humidity (RH) inside sealed packages to allow immediate visual inspection of whether it has sustained unsafe humidity levels.
Why I need choose your product?
Existing humidity indicator cards found in the market are impregnated with a chemical called cobalt chloride In the dry state, cobalt chloride is blue in color. After absorbing moisture cobalt chloride changes to pink color. A recent amendment made to the European CEE directive 67-548 pertaining to the Classification, Packaging and Labeling of dangerous materials, has classified cobalt chloride as a carcinogenic material. Improper handling of items containing carcinogen may cause health hazards and environment hazards, thus, goods containing cobalt chloride will not meet EU standards.
Our new range of humidity indicator cards are carcinogen-free and meet EU standards and color change can be blue to pink, yellow to azure, blown to green.
Advantage:
Reversible
Competitive price
Bright color; high recognition
Meet ROHS, EU standards, SGS
A back film to prevent chemical to reverse to your products
Using environmentally friendly ink and moisture-sensitive chemical
Usage :
1. The humidity indicator spots will change from blue (dry condition) to pink (humidity condition) as the relative humidity changes in the volume of air surrounding the indicator.
2.Relative humidity is indicated at the lavender color.
3.Indicator spots will change within eight hours of being exposed to a change in relative humidity.
4.The humidity indicator spots are reversible, and the pink spots will change back to blue when the volume of air is dried. Humidity indicator cards with pink or lavender spots can be returned to a blue color by placing indicators in a sealed container with 33 grams (1 unit) of desiccant for four hours. However, we do not recommend reversing or using cards that have been exposed to high humidity in excess of 60 percent.
5.The highest humidity indicator spot should be blue before being put into use.
6.The humidity indicator will be at its most accurate at a temperature of 23 degrees Celsius 72 degrees Fahrenheit.
7.Avoid contact with indicator spots. Wash any irritated areas with clean water.
