Problems solved by technology

[0003] Existing sensors are expensive, require high machining accuracy, high cost, and complex structures. Sensors are important components for robots to ingest environmental information. If the sensor is expensive, it will be the threshold for the popularization of robot technology and hinder the intelligent era. The development of the Chinese nation hinders the development of the great rejuvenation of the Chinese nation. The development of various low-cost sensors is very necessary for the development of robotics and smart cities.
[0004] The more sensitive the sensor is, the more accurate it is, and the easier it is to sense small environmental changes. The more sensitive the sensor, the better the high-speed response of the device. The existing high-sensitivity sensors are very expensive.

Embodiment 1

[0026] Embodiment 1. The sensor is characterized in that it includes a package housing (S1), a first photoresistor (R1), a second photoresistor (R2), a circuit (S3), and a transparent window (S2);

[0027] The circuit (S3) is installed in the package housing (S1);

[0028] The transparent window (S2) is installed on the package casing (S1) as a light-transmitting window, the entities of the first photoresistor (R1) and the second photoresistor (R2) are installed side by side in the package casing (S1), and the external light The same light spot can shine on the surfaces of the first photoresistor (R1) and the second photoresistor (R2) at the same time;

[0029] When the light spot moves, the light increments received by the first photoresistor (R1) and the second photoresistor (R2) are opposite, one is positive and the other is negative, which serves to amplify the moving information of the light spot;

[0030] The circuit (S3) has an amplification function;

[0031] The fir...

Embodiment 2

[0043] Embodiment 2. An intelligent robot has the aforementioned sensors.

[0044] attached Figure 2-3 Explanation, R5, R1, operational amplifier U1A form an inverse amplifier circuit, R4, R2, operational amplifier U1B form an inverse amplifier circuit, where R4 and R5 have the same resistance, and the input voltage of the inverse amplifier circuit is 5V , the circuit gain is -R1 / R5 and -R2 / R4, considering R4=R5, so the voltage at P1-2 is -5V*R1 / R5, and the output voltage of P2-2 is -5V*R2 / R5. R3, R6, R7, R8, and operational amplifier U2A constitute a differential amplifier circuit, R3=R6=15k, R7=R8=5k, and the circuit gain is 5k / 15k=1 / 3. So Vout=1 / 3*(Vp12-Vp22)=5*(R2-R1) / (3*R5).

[0045] What is not described in detail is prior art, so it will not be described in detail.
