This module depends on the BCM2835 library that must be installed on your board before you can actually use this module. To initialize the sensor, you have to specify the sensor type and the GPIO pin where the sensor is connected to. It should work for DHT11, DHT22 and AM2302 sensors.
Profit comes from leasing these drill rigs at contracted day rates that exceed the company's cost of capital and operating costs. The offshore drilling companies are leveraged to long term price trends of oil. It is often stated that the break-even for deepwater drilling is oil over $70 a barrel.he reason it matters is because day rates and operating costs are vastly different. Day rates are typically $75,000 per day for jackups, and $400,000 or more a day for deepwater (rates vary widely, based on market conditions and rig availability).
Then there is the original cost of the ship, which can be anywhere from $600 to close to $1 billion. These rigs usually last 30-35 years, which works out to a per-day cost of $59k (again, shows up as depreciation).Current day rates for these types of ships are running around $550k/day.This is the cost to the oil company to rent the ship from the owner, companies like Transocean or Noble Corporation.hese rigs usually last 30-35 years, which works out to a per-day cost of $59k (again, shows up as depreciation).
