The output of the LM335 is 10 millivolts per degree C, with 25 degrees C corresponding to 2.982 VDC. A reference circuit provides a zero reference voltage. It is adjusted to (2.982 volts - (25 degrees x 10 millivolts/degree) = 2.832 volts. To read the temperature of the LM335 directly in degrees C, connect the + lead from a high impedance DVM to the output pin and the - end of the DVM to the 2.732 volt pin. อ่านต่อและดูวงจร [...] [...] เกี่ยวกับวัดอุณหภูมิ ด้วยไอซี LM335 น่าสนใจดีครับ The circuit consists of two parts: The LM335 and its adjustment.
