Remote controlled Home automation without using microcontroller (Part-2) Schematic Circuit Diagram

This is the second part of home automation without using a microcontroller. In the previous part, we have designed a remote controller using RF module. And again if you do not have RF module on Proteus you can download from this link Rf module electronify  Now in this section we will connect the necessary home appliance to[…]

infra-red controlled remote switch

Nowadays, several manufacturers produce ICs that combine an infra-red receive LED with associated amplifier and demodulator. The type SFH505A from Simens used in present circuit has, in addition, a band-pass filter to minimize any interface. It is best used in conjunction with an infrared transmitter in the next article. The output of IC1  is limited to a[…]

UHF remote control receiver

The receiver is intended primarily for use with the remote control UHF transmitter described in the preceding article. It is a super-regenerative type with an active RF amplifier, T1. The antenna signal is applied to the input inductor via a BNC socket, The input circuit is tuned by trimmer C4. The amplified RF signal is[…]

UHF remote control transmitter

This low-power UHF FM transmitter is intended for remote control applications such as garage doors and wireless alarm systems. It is a single transistor design that operates at a frequency reserved for low-power wireless signaling. The operating frequency is determined by a resonator, F1. The following types may be used: UK: Type 82528 for 418[…]
