UK Deliveries
- If you live on the UK mainland and don't have any large materials or lithium batteries in your order it will cost £3.95 (£4.74 including VAT) if you spend less than £40 (£48 including VAT).
- If you spend between £40 and £200 (£48 - £240.00 including VAT, excluding large materials or lithium batteries) delivery is free to most locations, £12 (£14.40 including VAT, excluding large materials or lithium batteries) to Northern Ireland and £15 (£18.00 including VAT, excluding large materials or lithium batteries) to UK remote locations. For a list of postcodes that will be charged the remote location rate: remote area list.
- If you spend over £200 (£240.00 including VAT, excluding large materials or lithium batteries) delivery is free within the UK.
Rest of the world
- These orders are sent via UPS, and the cost is dependant on the service you choose at checkout. Alternatively you can choose the free collection option and have your own courier collect it from us. International orders can only be shipped to the registered card address. Please note: International orders may be charged import duty dependant on local import laws and duty rates. These charges are usually billed to you directly from UPS.
- Delivery times vary for international orders depending on the service selected and the destination. You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.

Q:
The data sheet for this humidity sensor HIH-4030-001 states a minimum load of 80Kohms. It is not clear if minimum load is referring to current, in which case the resistor value should be less than 80K, or minimum resistance, the resistor should be no lower than 80K?
Asked by: Andy Taylor
A:
I'd agree that the datasheet isn't that helpful. Since it states a minimum load, you need to provide a minimum load of 63uA (I = V / R = 5 / 80000) so an 80K resistor or a lower resistance to give a higher load. If you are trying to keep the current consumption low then you want to get as close to 80K as you can. If you're running off a power supply then using a 10K or whatever you happen to have to hand should be fine.
