Software engineers are divided into two specialties: computer application engineers and computer systems engineers. Computer application engineers analyze the needs of the user to design, create and maintain broad-focused computer application software or specific use programs.
Measure Temperature using Thermistor Thermistors are widely used because of their sensitivity, small size, ruggedness and low cost.Thermistors have an electrical resistance that varies non-linearly with temperature.easure Temperature using Thermistor Thermistors are widely used because of their sensitivity, small size, ruggedness and low cost.Thermistors have an electrical resistance that varies non-linearly with temperature.
where T(R) is the temperature of the thermistor as a function of its resistance R, is the temperature of the surroundings, and K is the dissipation constant, usually expressed in units of milliwatts per degree Celsius. At equilibrium, the two rates must be equal.f is positive, the resistance increases with increasing temperature, and the device is called a positive temperature coefficient (PTC) thermistor, or posistor. If is negative, the resistance decreases with increasing temperature, and the device is called a negative temperature coefficient (NTC) thermistor.
