  • UCTRONICS 4-20mA Signal Generator, Upgraded DC ±10V 0-20mA Current Voltage Analog Simulator, Built-in Rechargeable Battery, for PLC Debugging, Servo Motors Speed Regulation, Light Dimmer
    Upgraded Function: 1. The range of output voltage is expanded to -10V to 10V, high recommended for the servo motors which needs positive inversion and consecutive speed regulation; 2. It can output real 0V, help the light dimmer control the lights to go out completely, and eliminate flutter when control the servo motor; 3. It adds functionality of call output values quickly, more convenient for rapid debugging and production. Power Supply: built-in rechargeable battery (charged via micro USB port), external micro USB-5V, external power DC 15-30V, each way makes the generator work Voltage Output: -10V-10V, precision is 0.01V; Current Output: 0-22mA, precision is 0.01mA; Rotate the encoder knob to adjust output voltage/current; The range of output voltage/current can be setc; Both of them can be calibrated; Adjust and set value types (voltage/current) depends on the displayed mode. Multiple Display: just push the small button to switch the display mode between voltage and current, you can also follow the instructions to switch 0-100 percent or 0-50HZ display. Product Dimension: 3.94” x 2.36” x 0.78” (100mm x 60mm x 20mm), thiner than the old version, more portable and convenient.

  • HiLetgo GY-906 MLX90614ESF Non-contact Infrared Temperature Sensor Module IIC I2C Serial for Arduino
    MLX90614 is an infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer. The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C. The user can configure the digital output to be pulse width modulation (PWM). As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120°C, with an output resolution of 0.14°C.
