Alot of them use a sonar-like sensors that emit soundwaves to help them "see".
Exploratory robots use motion, heat, and camera sensors.
three disadvantages cyanmethemoglobin
tactile cells
Advantages-Many things are controlled by infrared. sensors are invisible to the naked eye and are very reliable. Disadvantages- Most infrared sensors must be lined up or they will not work
The advantages of light sensors is that they are really good security systems. The disadvantage of them is that they're really easy to set off.
It's situation dependent.
SENSORSAdvantages:It can accomodate new devices at anytime.Very accurate.Disadvantages:Expensive .Self heating.
Some disadvantages of light sensors include susceptibility to interference from ambient lighting conditions, limited accuracy in distinguishing between different light intensities, and potential degradation of performance over time due to environmental factors like dust or humidity. Additionally, light sensors may not be suitable for applications requiring precise detection in rapidly changing light environments.
One of the biggest disadvantages of large scale wireless sensor networks is the fact that they are vulnerable to unauthorized access. Also it relies on the complexity of logistics involving selective replacement of sensors.
The disadvantages of a distributorless ignition system are a susceptibility to heat damage, a difficulty in diagnosing solid state electronics, and more reliance on sensors. If one sensor shuts down, the entire system will fail.
Advantages:- They generate a voltage proportional to the velocity the crystal is deformed so require no local power source. Disadvantages;- They are high impedence and can pick up stray voltages in the connecting wires. The crystal is also prone to cracking if overstressed
Zigbee technology has many different advantages and not a lot of disadvantages. Some advantages include lower costs and it can work in any type of market even with low power sensors. A disadvantage is that it is a bit slower than other technologies.
Smart sensors include environmental sensors (such as temperature and humidity sensors), motion sensors, light sensors, proximity sensors, and biometric sensors (such as fingerprint or facial recognition sensors). Each type of sensor is designed to detect specific physical characteristics or conditions and provide data for various applications.
There are many types of sensors in cars. Some include parking sensors, blind spot monitors, water sensors, and tire pressure sensors, temp sensors, oil pressure sensors, Oxygen sensors, .
The advantages of inductive proximity sensors areThey are very accurate compared to other technologiesHave high switching rateCan work in harsh environmental conditionThe disadvantages of inductive proximity sensor areIt can detect only metallic targetsOperating range may be limited
