4Pcs Digital 38khz Ir Receiver Sensor Module 4Pcs 38khz Ir Transmitter Sensor Module Kit for Electronic Building Block

In a comprehensive review of the Dorhea 4Pcs Digital 38khz Ir Receiver Sensor Module and 4Pcs 38khz Ir Transmitter Sensor Module Kit, there were mixed experiences and reception. Several customers expressed disappointment with the transmitter, citing issues such as a limited range, poorly aligned LEDs, and inadequately connected pins. They highlighted that the module lacked the necessary electronics to boost the data signal, making it unsuitable for use with Arduino or ESP projects. One customer even attempted to use a PN2222 transistor but found it to be insufficient, rendering the module effectively useless. However, there were positive experiences as well, with a customer successfully using the modules on a Raspberry Pi Zero W for a specific purpose. They were able to set up the receiver and transmitter individually and achieved the desired functionality for their project. They highlighted the need to use GPIO pins for the signal and expressed satisfaction with the product's performance for their intended use. Despite the mixed reception, these IR sensor modules may have potential for specific applications and projects, particularly when paired with compatible devices such as the Raspberry Pi Zero W. **
