LDR Light Dependent Resistor | Light Sensor 3mm
LDR are chemical based resistors that can change their resistance on exposure to the light. The LDR usually has very high resistance, in absolute darkness, on exposure to light the resistance immediately drops. Drop in resistance is proportional to the intensity of light.

50kg Half-bridge Experiments Body Scale Load Cell Sensor
The 50kg Half-bridge Experiments Body Scale Load Cell Sensor is measuring; the correct force is applied to the outer side of the strain E-shaped beam portion of the sensor (i.e., a strain gauge affixed to the intermediate, adhesive coating with white beam arms); and the outer edges to form a shear force in the opposite direction, i.e., middle strain beam bending necessary changes can occur under stress, strain beam side by another force should not be a barrier.
The sensor can be used with  the following three methods
  1. Using a sensor with an external resistors full bridge measurement range of a sensor range: 50kg. Higher requirements for an external resistor.
  2. The uses of only two full-bridge sensors measuring range are the range of the two sensors and: 50kgx2 = 100kg.
  3. The use of four full-bridge sensors measuring range is the range of four sensors and: 50kgx4 = 200kg.

Features :

  1. Internal 1000Ohm half-bridge strain gauge load cell, the range is 50kg, half-bridge structure.
  2. Widely used in hopper scales, platform scales, platform balance, belt scales, and other electronic weighing devices.

LM35 Temperature Sensor | Analog
The LM35 series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 device does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C temperature range. Lower cost is assured by trimming and calibration at the wafer level. The low-output impedance, linear output, and precise inherent calibration of the LM35 device makes interfacing to readout or control circuitry especially easy. The device is used with single power supplies, or with plus and minus supplies. As the LM35 device draws only 60 µA from the supply, it has very low self-heating of less than 0.1°C in still air. The LM35 device is rated to operate over a −55°C to 150°C temperature range, while the LM35C device is rated for a −40°C to 110°C range (−10° with improved accuracy).

Features

  • Calibrated Directly in Celsius (Centigrade)
  • Linear + 10-mV/°C Scale Factor
  • 0.5°C Ensured Accuracy (at 25°C)
  • Rated for Full −55°C to 150°C Range
  • Suitable for Remote Applications
  • Low-Cost Due to Wafer-Level Trimming
  • Operates From 4 V to 30 V
  • Less Than 60-µA Current Drain
  • Low Self-Heating, 0.08°C in Still Air
  • Non-Linearity Only ±¼°C Typical
  • Low-Impedance Output, 0.1 Ω for 1-mA Load
