Photoconductivity sensors, also known as photoresistors or light-dependent resistors (LDRs), are a type of light sensor that changes their electrical conductivity in response to variations in light intensity. These sensors operate on the principle of photoconductivity—where a material’s ability to conduct electricity increases as it absorbs light energy.

Pet odors can stem from various sources such as waste, fur, saliva, litter boxes, and even from food residue. If not addressed effectively, these odors not only cause discomfort but may also indicate underlying hygiene or health issues. Conventional deodorizing solutions may provide temporary relief, but they rarely offer a proactive approach to odor detection and management.

Carbon dioxide (CO₂) is a colorless, odorless gas that is essential for life on Earth. It plays a crucial role in the carbon cycle, supports photosynthesis in plants, and is a major greenhouse gas contributing to climate change.

R410A is a widely used hydrofluorocarbon (HFC) refrigerant that has replaced older refrigerants like R22 in residential and commercial air conditioning systems. Known for its high cooling efficiency, zero ozone depletion potential (ODP), and improved environmental performance, R410A has become the industry standard for many HVAC applications.

R-32 (difluoromethane) is a widely used hydrofluorocarbon (HFC) refrigerant known for its low global warming potential (GWP) and high energy efficiency.

R-134a (tetrafluoroethane, C₂H₂F₄) is one of the most widely used hydrofluorocarbon (HFC) refrigerants in the world. Introduced as a replacement for R-12 (dichlorodifluoromethane, CFC-12) in the 1990s, R-134a gained popularity due to its non-ozone depleting nature.

A pressure sensor is a device used to measure pressure in gases or liquids. It converts pressure into an electrical signal that can be monitored, recorded, or analyzed. Pressure sensors are used in a variety of applications, including industrial automation, medical devices, automotive systems, and environmental monitoring.

The world of technology is evolving rapidly, with one breakthrough following another. OpenAI’s ChatGPT has sparked a new wave of AI innovation, Tesla’s humanoid robot Optimus has made its debut, and NVIDIA’s CEO Jensen Huang boldly declared that "the next AI revolution will be embodied intelligence."

An industrial CO₂ sensor is a device designed to measure the concentration of carbon dioxide gas in the atmosphere. These sensors are essential in environments where CO₂ is a byproduct or where high concentrations of the gas may accumulate, posing a potential risk to human health, safety, and the environment.

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is highly dangerous when inhaled, as it can lead to poisoning or even death. It is produced by the incomplete combustion of carbon-containing fuels, such as gas, oil, coal, and wood.
