Description for LM35DZ
LM35DZ is one of LM35 series integrated circuit sensor used for temperature sensors because of their high precision. The LM35DZ IC output signal and the temperature Celsius are linearly proportional giving the IC advantage over other temperature sensors. The LM35 series has many styles for packaging but TO-220 is the most common for LM35DZ.
The sensitivity of the LM35DZ is 10 mV/°C. The output voltage is affected by the temperature in a direct proportional way, as the temperature increases the output voltage also increases. The temperature sensor converts the measured input temperature into electronic data which is inform of voltage. There two type of sensors contact and non-contact which uses infrared.
Pin configuration of LM35DZ
LM35DZ is made of the pins supply voltage, ground and output pin. The middle pin is the analog output.
The input pin Vs voltage rage (4 to 20V), the output pin (0mV +10mV/℃)

Features and specifications for LM35DZ
● Low current drain of 60μA
● An accuracy of ± 0.5℃
● Low cost because of the Wafer level of trimming
● Operation voltage range of between 4 to 30V
● Low output impedance
● Temperature and output voltage of pin 2 are directly proportional.
● Wide range of temperature operation - 55℃ to 150℃
● Smaller in size which makes appropriate for application in for devices in remote area.
● The IC is available in the following packages TO-CAN, SOIC, TO-220 and TO-92

Working of LM35DZ
The output of LM35DZ integrated circuit keep varying because its affected by the temperature around. Due to its high precision the IC can be integrated with Arduino or microcontroller. Voltage of 5V is supplied through the Vs input terminal and the ground terminal is connected to the ground of the circuit interfaced with. The temperature is measured in analog form (voltage form).
The voltage is convertible from analog form to digital form, the temperature form by the equation
Vout = 10 mV/℃ × T
Where T is the temperature
Application of LM35DZ
● Heating ventilation and air conditioning (HVAV) is for ensuring fresh air in the building which help improve human productivity in their work. Good ventilation ensure odor and pollution are reduced in the building.
● Power supply the LM35DZ have wide range of voltage supply of between 4 to 30 V making it ideal for many applications.
● Battery management charging and discharging of batteries pack need protection therefore battery management system (BMS) is required. Battery management system ensures the following: battery longevity and safety, show the battery end of life, give caution when there is a fault like imbalance of cell.
● Temperature measurement the high precision of the IC makes it the best in application for measuring temperature of a certain environment and devices/components.
● Shutting down system breaking the circuit to prevent damage.
