IR and RF sensors
The density of brickwork can vary depending on the type of bricks used and how they are stacked. On average, the density of brickwork is around 120-150 pounds per cubic foot (1920-2400 kg/m³).
To calculate the density of bricks, divide the mass of the brick by its volume. The density of bricks is typically around 1,500-2,000 kg/m^3 depending on the type of material used.
The density of austenitic steel varies according to the type or grade. For one of the commonly used austenitic steel like Type 304, the density is 8.0g/cm3.
The density of bitumen used in HDM50 typically ranges from about 1.0 to 1.2 grams per cubic centimeter (g/cm³). This density can vary depending on the specific formulation and temperature of the bitumen. HDM50, a type of bitumen used in road construction, often has a density around 1.1 g/cm³. Always refer to specific product data sheets for precise values.
The three types of sensors commonly used in a greenhouse weather station are temperature sensors to monitor air and soil temperature, humidity sensors to measure moisture levels in the air, and light sensors to track the intensity and duration of sunlight reaching the plants.

Strain gage based sensors are mostly used.
Traffic light poles can vary in weight depending on their size and material, but on average they weigh between 100-300 pounds. The weight can also be influenced by factors such as the type of traffic light, the materials used in construction, and any additional features like cameras or sensors.
A traffic signal is controlled by a control box on the side of the intersection, the control box receives data from electromagnetic sensors under the pavement, and that data is processed by amplifiers inside of the box and the traffic controller makes the appropriate decision on what to do. So to answer the question, the traffic light is a decision made by the traffic controller which is a output.
It has capacitance type
all of them. (why would they put a type of sensor in a car that WASN"T used?)
Pressure sensors at intersections are devices embedded in the road surface that detect the weight of vehicles passing over them. They are commonly used to monitor traffic flow, manage signal timings, and improve overall traffic management. By providing real-time data on vehicle presence and counts, these sensors help optimize traffic light cycles, reduce congestion, and enhance safety for both drivers and pedestrians. Additionally, they can contribute to smart city initiatives by integrating with broader transportation management systems.
There are potentiometers, resistors, hall effect switches, piezoelectric,

Sensors are used to detect things, such as motion, light, or color.
