Developed Five-Wire technology with the harshest environments in mind, so it's no wonder that it excels in reliability, durability, and expected product life. Impervious to environmental conditions such as liquid spills and splashes, humidity, and washdown, these screens are the most contamination-resistant available. They deliver drift-free operation for a lifetime of 35 million finger touches.

Thermistors are inexpensive, easily-obtainable temperature sensors. They are easy to use and adaptable. Circuits with thermistors can have reasonable output voltages - not the millivolt outputs thermocouples have. Because of these qualities, thermistors are widely used for simple temperature measurements. They're not used for high temperatures, but in the temperature ranges where they work they are widely used.

  Inch product description 100 percent brand new and high quality using a wide voltage lm393 comparator with a mounting screw hole, easy to install using the sensitive type photosensitive resistance sensor the comparator output signal clean waveform is good, driving ability than 15ma with adjustable potentiometer can adjust the brightness of the light detected working voltage: 3. 3V 5v output: do digital switch output (0 and, ao analog voltage output usage: this module is sensitive to the light, usually used for detecting the ambient brightness and light intensity. When there is no light or the light intensity can not reach the value, do output is high level. When light intensity over the value, the module does output is low level. The module digital output do can be directly connected with the microcontroller, use a microcontroller detect high or low level, so that can detect the environmental light intensity change. Can use this board digital output do port drive relay module directly(our store on sale these relay modules), can also use as a photoelectric switch. The analog output ao connects with the ad module and it can get more precise light intensity value through the ad converter. Specifications: board color: blue board size: approx. 3. 2Cm x 1. 4Cm/1. 26 x 0. 55 Inch package includes a 1 x lm393 LDR sensor inch.

Capacity : 25 / 50 /100 kgf · Overall Accuracy : ± 0.25% FSD Application · Rubber o rings allows easy mounting over foot pedal.
