According to a new market research report "Automotive Temperature & Humidity Sensor Market by Technology (CMOS, MEMS, TFPT), Packaging Type (SMT, Pin Type), Application (Powertrain, Body Electronics, Alternative Fuel Vehicle), & Geography - Forecast to 2020", published by MarketsandMarkets, the Automotive Temperature & Humidity Sensor Market size was worth $1084.38 Million in 2013 and is expected to reach $2129.68 Million, at a CAGR of 11.05% between 2014 and 2020.
In the automotive industry, temperature & relative humidity sensors are used for various applications. These include powertrain, body electronics, and alternative fuel vehicles (AFV). Smart sensors offer many advantages over conventional sensors such as high performance and accuracy coupled with low cost, easy implementation, no requirement for complex calibration, and low power consumption among others.
The following is a list of the most significant items that contribute to OR. These must be kept in mind when thinking about engine OR.
1. Compression Ratio...Higher requires more octane
2. Cylinder bore...Bigger bore requires more octane
3. Cast iron heads...Needs more octane then aluminum heads
4. Restrictor plates...Less restriction requires more octane
5. Lean mixtures...Need more octane
6. Coolant temperature...Higher needs more octane; 160 ° is ideal
7. Spark advance...More spark advance requires more octane
8. Intake air temperature...High temperature needs more octane
9. Humidity...dry air (low humidity) requires more octane
10. Barometric Pressure...Higher needs more octane
11. Altitude...Closer to sea level needs more octane
