9800 Direct Reading Spectrometer
The Shimadzu ICPE-9800 is a full-spectrum direct-reading inductively coupled plasma optical emission spectrometer (ICP-OES) engineered for high-throughput, multi-element trace metal analysis in environmental, pharmaceutical, geological, and industrial quality control laboratories. Designed for routine and production laboratory testing, the CX-9800 optical emission spectrometer combines Paschen-Runge optics with high-resolution. The CREATE CX-9800 Direct Reading Light spectrum instrument adopts the full spectrum vacuum type Optical inspection system of Paxing-Runge structure, and the measurement Wavelength range is 160~800nm. The CX-9800 is suitable for a variety of metal substrates. Domestic manufacturer of vacuum CCD/CMOS full-spectrum technology spectrometer; 3.

ESP relay module optocoupler
It features a 30A relay, optocoupler isolation for enhanced safety, and supports both high and low trigger signals. This module is ideal for projects requiring the control of high-current loads using low-power microcontrollers like Arduino, Raspberry Pi, or other development. Most modules include an optocoupler for isolation, so the relay coil doesn't share ground with your ESP32. Some won't trigger reliably at 3. I recommend the 4n37, which are quite robust. In figure 1 on the left you can see the first circuit I tried, using the following code: name: esp-32-try board: wemos_d1_mini32 - platform: gpio id: try_in pin: number:. The relay is a programmable switch that can be used to control ON/OFF electrical devices. WARNING Safety first! Safety first! Please be careful when working with high voltage.
