LDR Photoresistors
We have photoresistors for sale! Light dependent resistor sensor is made of semi conductor material, and the conductance changs with light. According to this characteristic, LDR photoresistors can be produced with different figures and illuminated area. LDR photoresistor is widely used in many industries, such as toys, lamps, camera, etc. The photoconductive resistance is a device ...

Linear Light Sensor
Linear Light Sensor, we also call it phototransistor. The chip integrated inside is very sensitive to light changes. So normally it is used to detect the current ambient light level and converts the light energy into an electrical signal output. Compared with traditional photoresistors, light sensor is more environment friendly and complied with ROHS requirements. We can also make it to be SMD ...

Providing Actionable LiDAR Point Cloud Deliverables and the Inertial Labs RESEPI
What is LiDAR Point Cloud? What is LiDAR Point Cloud? Components Overview A LiDAR point cloud deliverable is a collection of millions (even billions) of points used to accurately map an environment, similar to how a pointillism painting creates a picture. Each of these points has a location in a known coordinate system (local or global), along with a value for the intensity, which ...

Delphi research assessment for popularising Compact Fluorescent Lamps in India
In continuation of our earlier work on popularising a seemingly perfect illumination technology, i.e. the compact fluorescent lamp (CFL), a Delphi study was undertaken with experts in lighting technology, backed with an intense focus group interaction to settle divergences and discordances noticed earlier, when the authors had recommended an aggressive implementation of the prescription for ...

Drones with night vision camera
Being able to see in the dark with a. drone with a night vision camera is a massive advantage when operations have to be conducted by people, especially when this can be done remotely. With the introduction of camera mounted drones most camera manufacturers have developed camera ‘cores’ which is basically just the working part of the camera with all the casing stripped away so that ...

Using air instead of water to separate your recycling materials
Separating recyclables by density is nothing new. For many years, the use of wet tanks to remove heavy materials from lights has been very successful. Unfortunately, the disadvantages of this technology are increasingly apparent. With stringent and increasing environmental regulations, use of water is quickly become a messy proposition. When material enters a wet tank, any contaminant on the ...

Choosing the correct PID lamp
The two most common lamps used in PhotoIonization Detectors (PIDs) are 10.6 eV and 11.7 eV lamps. The 11.7 eV lamp measures the broadest range of compounds while the 10.6 eV lamp is more selective. To allow higher energy light to pass through, 11.7 lamps are manufactured with a cylindrical window (the flat surface at the top of the lamp) that deteriorates quickly – even when not in use. ...

Smart operation of air-conditioning (A/C) and lighting systems for national load management
In the countries of Arabian Peninsula, demand for electric power, primarily controlled by the air-conditioning (A/C) and generally peaking at 15:00 h, is currently growing well over 5% annually. Adaptations of smart operation of A/C and lighting systems in government and institutional buildings that commonly function between 07:00 h and 14:00 h has been evaluated as a technique for national load ...

Effects of operation conditions on removal rate constant and quantum yield of gaseous chlorobenzene degradation in a photochemical reactor
A photochemical reactor with a low-pressure mercury ultraviolet (UV) lamp was established to treat waste gas containing chlorobenzene. Operation conditions such as light intensity, gas humidity, and inlet chlorobenzene concentration were varied. Two significant parameters, the removal rate constant and the quantum yield (relating to removal kinetic and light energy utilization), were investigated ...

Inside the Gas Analyser – the Spectrometer
The measurement principle of several types of OPSIS gas analysers is called DOAS, which stands for differential optical absorption spectroscopy. A key component of the analyser is the “spectrometer”, a unit which separates incoming light into its individual wavelengths for subsequent recording of the light spectrum. But how does a spectrometer work?The key is an optical component called a ...

Solvent-free oil-in-water analysis
Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

Plastic Additives: Polymer Stabilizers, Plasticizers and Lubricants
During the manufacturing of polymeric materials, such as plastics and rubbers, a number of chemical additives are added to inhibit or retard their degradation or to achieve better product quality. Heat stabilizers, antioxidant, UV absorber, plasticizers and lubricants are the most commonly seen and widely used additives. Heat stabilizers Heat stabilizers are mainly used for polyvinyl chloride and ...

ION Science PID Response Factors
PID Response Photoionization Detectors (PIDs) respond to a broad range of organic and a few inorganic gaseous and volatile chemicals (‘volatiles’). In order for PID to respond to a volatile, the photon energy of the lamp must be greater than its ionization energy (IE). ION Science PIDs are available with lamps emitting light of maximum energy of 10.0 eV, 10.6 eV, and 11.7 eV. This ...
