Discussion Overview
The discussion revolves around the search for a 1.5-volt in-line or pigtail day/night sensor suitable for an outdoor garden ornament powered by solar-charged batteries. Participants explore various technical aspects, including communication standards, circuit options, and the functionality of the sensor in relation to the ornament's operation.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant initially miscommunicated the voltage requirement, clarifying later that they need a 1.5-volt sensor.
- Several participants inquire about the preferred serial communication standard for the sensor, suggesting options like SCI, SPI, and I2C.
- There is a discussion about the limitations of finding a sensor that operates at 1.5 volts, with some suggesting alternatives like using a 5V sensor with a power supply module.
- Participants discuss the functionality of the garden ornament, questioning whether it operates at night and suggesting larger batteries for extended life.
- One participant proposes using the solar cell itself as a day/night sensor in addition to its charging function.
- Concerns are raised about connecting batteries in parallel and the implications of mismatched batteries.
- There is a query about the opposite function of a photocell, leading to the discovery of a reverse photocell, with a request for wiring advice.
- Participants share wiring instructions for connecting the photocell, with some expressing confusion about electrical terminology.
- Testing results are shared, indicating issues with the photocell's output and suggestions for troubleshooting, including the need for a load to be connected.
- One participant expresses frustration over the photocell not functioning as expected and the lack of response from the seller.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best approach to achieve the desired functionality of the sensor and the garden ornament. Multiple competing views and suggestions remain throughout the discussion.
Contextual Notes
Participants express uncertainty regarding the specifications of the photocell and its compatibility with the 1.5-volt requirement. There are unresolved questions about the wiring and functionality of the proposed solutions.
