HPD05 Infrared PM2.5 Sensor Module Product Details 1. Module List HPD05 Module 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. 4.

The GSM interception system allows for real-time interception of telephone conversations and text messages sent through a GSM network. It is compatible with GSM 850/900/1800/1900 network and base transceiver stations all over the world. The GSM interception system supports A5.1 and A5.2 encryption algorithms used to encode phone calls over GSM networks. The system's range of operation has a radius of about 2 km, which can be extended up to 5.5 km with additional 50W power amplifiers. The GSM interception system is able to intercept 48/96 target phones simultaneously (with the ability to expand the system to support greater number of targets), depending on RF channels and the number of communication modules (in passive mode). Intercepted calls and text messages can be recorded and subject to further analysis. The device is operated through a PC software suite, included in the package.

Film Shrinkage Test Equipment Film Shrinkage Tester GBK-D1 Film Shrinkage test, known as linear thermal shrink test or free shrink test, is used for analyzing the effect of temperature on heat shrinkable films made from polyethylene, ethylene copolymers and their mixtures. Basically, shrinking force, contracting force and shrinking ratio can be measured in such determination. GBPI Film Shrinkage tester conforms to the multiple national and international standards: ASTM D2732 - Standard Test Method for Unrestrained Linear Thermal Shrinkage of Plastic Film and Sheeting ISO 14616 - Plastics Heatshrinkable films of polyethylene, ethylene copolymers and their mixtures Determination of shrinkage stress and contraction stress DIN 53369 - Testing of plastic films determination of the shrinking stress Film Shrinkage Test Equipment GBK-D1 is used to determination of the degree of unrestrained linear thermal shrinkage and dimensional stability at different temperatures. Widely used in industries of plastic material, plastic products, petroleum, chemicals, research institute, inspection agency and so on. Principle This tester uses the principle of air heating to connect the tested sample to the tension sensor and displacement sensor. After reaching the maximum shrinkage force, it is placed in an external test environment with an ambient temperature of 23 to cool down. The reference temperature, shrinkage force and displacement are recorded, and the recorded data can be used to determine the optimal shrinkage conditions of the film.
