Disadvantages of electrochemical sensors include:
- Narrow or limited temperature range.
- Short or limited shelf life.
- Cross-sensitivity of other gases.
- The greater the exposure to the target gas, the shorter the life span.
What are disadvantages of sensors?
Advantages are their accuracy, low cost, and high performance etc. Disadvantages are that they can be affected by environmental changes and contamination, e.g., a gas that they are measuring can affect the performance of the sensor [5].
What are the disadvantages of a sensor circuit?
Disadvantages of Light sensor
?LDRs are highly inaccurate with high response time (about 10s or 100s of milliseconds). ?Resistance varies continuosly (analog) in photoresistor and are rugged in nature. ?Photodiodes are temperature sensitive and are uni-directional unlike photoresistors.

- Reduction of cable trip hazards in the depends upon performance space.
- Avoidance of cabling problems common with wired microphones, caused by constant moving as well as stressing the cables.
What are the challenges of wireless sensor networks?
Challenges in such WSN include high bandwidth demand, high energy consumption, quality of service (QoS) provisioning, data processing and compressing techniques, and cross-layer design.
What is the disadvantage of the piezoelectric pressure sensor?
Explanation: The disadvantage of the piezoelectric pressure sensor is that it can only give the pressure difference. The advantages of the piezoelectric pressure sensor are quick frequency response and they are of small size.These are only used for the low-frequency measurements.
What are light sensors made of?
Typical applications of Phototransistors light sensors are in opto-isolators, slotted opto switches, light beam sensors, fibre optics and TV type remote controls, etc. Infrared filters are sometimes required when detecting visible light.
What are the advantages of pressure transducers?
